Fix Google Tag Manager Conversions

My Tag Manager container is already on the site, yet none of the conversion events are coming through. The sole goal is to track website conversions reliably, and right now they show zero in both Google Analytics and Google Ads even though real sales are happening.

Here’s what I need:
• Diagnose why the conversion tags are not firing or not reaching GA 4 and Google Ads.
• Repair or rebuild any triggers, variables, or data-layer pushes so the events appear in GTM’s Preview mode and populate in GA 4 Realtime, standard reports, and the Google Ads conversion column.
• Provide a brief hand-off note describing the fix, so I can replicate it on future tags.

Acceptance criteria
1. Conversions fire in GTM debug with correct parameters.
2. Events register in GA 4 within the same session.
3. Google Ads receives the conversion and attributes value correctly within 24 h.

If you’re comfortable diving into GTM containers, GA 4 event setup, and Google Ads conversion tags.
