I am having trouble getting my GTM tags to fire consistently. I’m using the gtag.js function gtag() to fire a tag when a user clicks a button on my page.
I don’t always see those tags on Google Analytics, so I went to GTM Preview tool to check out what is wrong. When looking at the preview, this is what I see for a particular tag that I’m testing. Keep in mind that I have GDPR protection set up, but I consented to the cookies, so I’m loading all the gtag/gtm scripts.

I’m fairly new to GTM , I successfully set up a simple form submission triggers. but I need it only to capture submissions if a certain radio button is click , I the logic , get the value but I don’t know how to implement this on GTM.

My custom html tag is

I have a table booking widget (3rd party) in one page of my website and I want to send the successful booking events to my GA4. I have the same GTM ID in my website and implemented in the vendor’s backend.

If I have custom database which I can send some PII data to, will Google be able to see what was the content of the function (e.g. the object I included there) I used to send it?

I am using injectScript API in GTM tag template to insert an external javascript into the website.
