Hi @uxmike, the merge tag is only used by Mailchimp, but I am not sure if it works in embed.js or not, that may be a question for Mailchimp. In Webflow, there is no process on the Webflow side which is merging that info, it is all exclusively done by mailchimp.
Webflow is simply making the link what you set the url to be and since the data is not being merged into the merge tag, the url is invalid.
I am not sure exactly how you have the Merge tag field setup at Mailchimp, but here is an article on how to use Merge tags: Getting Started with Merge Tags for Email | Mailchimp
You might need to get a custom coder to help with this, some places to get help would be:
- The Webflow Experts: When you need expert help with a Site project, usually when you need a designer to build a full site, but can also be for small things you may need help with.
- Sixty. Sixty is a pay by the minute service, I would recommend when you need small coding jobs to do, like some script work, or could also be for design help.
I hope this helps.
