HELP! Dynamic Template - [400] Bad Request: ValidationError

Hey Everyone!

I am trying to use a dynamic template with

I am getting the following error: “[400] Bad Request: ValidationError” whenever I try to pass through a merge field for the length of an audio file.

Any ideas for how I can fix this?

If I delete the merge field for the length and just leave it as a set number within the template, it works fine. But, when I try to run it with a merge field that sets the length, it fails.

Please help! Thank you :slight_smile:
