Modify strings - User Selector fields feeding into Post Builder

Support Discourse Custom Wizard
1

Likely a case of me misreading the documentation but I’d love a pointer in the right direction for how to modify field outputs that end up in a post!

Background: Currently making a form for my org’s bi-annual Convention to handle submissions from our membership and we’re looking to have submission authors names included on each item, including their forum handles. I’m using the User Selector drop-down field to accomplish this.

Steps:

  1. User fills out the /2025-convention-resolution-submission Custom Wizard. In the process they add the various resolution authors forum users via the User Selector drop-down
  2. Custom Wizard Creates a Topic and uses the post builder, which contains the following line: @w{step_4_field_2}

Expected Output:
@$USER for single author submissions
@$USER,@$USER2 for multi author submissions

Output:
@$USER for single author submissions
@$USER,$USER2 for multi author submissions
