Help me fix a parameter problem with my google ads setup

Job ID: 31956438

Budget: $30 – $250 AUD

I'm getting this error

Your campaigns can't tailor dynamic ads based on user activity when your audience source doesn't send the required parameter. Make sure the required parameter is being sent correctly.
Your audience source may not have the required parameter for your business type on all relevant pages or events. Check that you're passing the required parameter for your business type anytime users interact with products or services you want to advertise. Note that Google Analytics refers to parameters for remarketing as Dynamic Attributes.

I've checked the set up with anayltics and it all looks ok.
