Webinar ID for GoToWebinar is not working on new landing pages

Hey,

 

i have a problem and was wondering if anyone has come across this before or has any insight on how to fix it.

 

we have created new landing pages for our webinars, but they don't seem to be working with GTW. if I remove the Webinar id in the triggers it registers in GTW and sets reg status but when I add the webinar id in the trigger it sets the status to sent and the leads record doesn't go into GTW.

 

I've to try cloning the old template and testing it and that doesn't work ( i thought if I stripped it back I could find out what missing in the code, but doesn't seem to be working)
