Google ads tracking conversion help!

Hi experts!

I would like tou edit the google ads tracking conversion on my shopify , but I met some troubles!

I have added the first event snippet about “User browses the web” and it did work . But when I continue to add second tracking event snippet about “Customer consultation or request for quotation” ,I can’t get any response from Google ads. I have tried so many ways to fix it , but it didn’t work .

What I have done :

1、I add the Global site tag on theme.liquid files .

2、I have added the event snippets on checking out setting .

Pls check the attachment and help me !
