Hello, I have created a Google Ads conversion tag but the trigger isn’t firing. I have checked it multiple times and it seems like it should work. The trigger logic is: Page URL regexp match ^https://www.fvdublin.org/in-person-event-registration-thank-you/?ad\_chid=.\*$ (which = “starts with”) In debug mode, this “thank you” URL is always there. Here’s an example string that the trigger doesn’t work on: Page Url “[Schedule A Tour | Senior Retirement Community | Columbus OH | Friendship Village of Dublin](https://www.fvdublin.org/in-person-event-registration-thank-you/?ad_chid=1766057151)” What might be happening here? ---

Hi! Just go with > [@David\_Culbertson](#): > > in-person-event-registration-thank-you with “contains” rule, I don’t see a need to use regexp here 🙂 or just “thank-you” as pattern, if you have multiple of thank-you pages Cheers! ---

“?” is a special character in Regex - if you want to match a literal “?”, you should escape it using “\?” So if you need to use this regex, I would try something like this: ```auto ^https://www\.fvdublin\.org/in-person-event-registration-thank-you/\?ad_chid=.*$ ``` ---

@sararekowska, I tried your REGEX then also tried simply contains “[Schedule A Tour | Senior Retirement Community | Columbus OH | Friendship Village of Dublin](https://www.fvdublin.org/in-person-event-registration-thank-you/?ad_chid=)” as recommended by @gonerator. Neither worked. Oddly, the internal form goal tracking works perfectly. To summarize: THIS WORKS FOR INTERNAL GOAL: URL contains [Schedule A Tour | Senior Retirement Community | Columbus OH | Friendship Village of Dublin](https://www.fvdublin.org/in-person-event-registration-thank-you/?ad+chid=) (side-note: goal tracking set-up uses “URL” while the tag manager uses “Page URL” - is there is a difference?) NEITHER OF THE FOLLOWING WORK FOR GAds TAG TRIGGER: Page URL regexp ^[https://www](https://www).fvdublin.org/in-person-event-registration-thank-you/?ad\_chid=.\*$ Page URL contains contains [Schedule A Tour | Senior Retirement Community | Columbus OH | Friendship Village of Dublin](https://www.fvdublin.org/in-person-event-registration-thank-you/?ad+chid=) What is going on on?? ---

I noticed that in the initial regex you mentioned there is “?ad\_chid”, but when I go to the website it’s “?ad+chid”. Can you try again with the plus sign? ---

@sararekowska I have no idea how you’re seeing “ad+chid” instead of “ad\_chid.” The platform on which the forms are built is ActiveDemand and it, similar to Google’s UTM codes, it only uses “ad\_chid” (explained in detail - [https://engage.activedemand.com/hc/en-us/articles/360047169913-Integrating-ActiveDEMAND-with-Google-Services](https://engage.activedemand.com/hc/en-us/articles/360047169913-Integrating-ActiveDEMAND-with-Google-Services)) I just checked the Piwik Pro pages report and did two searches for the past 30 days: URL contains “ad\_chid”: 106 URLs found URL contains “ad+chid”: 0 URLs found Perhaps your browser is doing something? Over the weekend, I compared the [fvublin.org](http://fvublin.org) domain’s trigger logic to the trigger logic in another domain in the same instance, [thebaileyatbridgepark.com](http://thebaileyatbridgepark.com). For both domains, I use the same exact trigger logic (URL contains) but FVD doesn’t work. I must be missing some minor detail. ---

The only difference I see are the multiplicity settings: ![image](https://europe1.discourse-cdn.com/flex005/uploads/piwikpro/original/2X/8/8dcaee2048907fd009be936f9d18e8467a3dc39a.png) Maybe that’s why it’s not firing properly? Or is it intended? ---

That fixed it! Having a Charlie Brown “that’s it!” moment right now! (for reference: [https://www.youtube.com/watch?v=F1VPJA3ZQwc](https://www.youtube.com/watch?v=F1VPJA3ZQwc)) This trigger’s purpose was to fire a GAds conversion tag but the trigger failed unless set to “many times” per session. Oddly, the trigger only fires once in my testing but that’s enough. ---

I’ve recently had a similar issue with the Multiplicity settings, the conversion was not firing even when I started a new session. I wanted to create a trigger for a specific page URL that only fires once per session, but then I was forced to switch to “Many times during a session”. ---

@joao The odd thing about the problem I encountered is that the trigger was not firing at all. In other words, when “once in a session” was selected, the trigger never fired. This seems to be a bug. ---

@David_Culbertson yes, that’s exactly what I encountered too, the conversion just wasn’t firing, and in the debug window I could see that it wasn’t firing because of this multiplicity condition. I didn’t spend a lot of time debugging this behaviour in great detail because I was running short on time, but it seemed like a bug to me too: maybe there is an issue with the cookie that stores this information? ---

I tried the setting on a couple of tags and it worked correctly - fired just once. Maybe in this case the session wasn’t closed yet? ---

No explanation, @sararekowska. I must have missed something during debugging but working fine now. ---
