Hey mdsmith1,
Thanks for reaching out to the Retool community. Allow me to help out on this Workflow start issue.
To trigger a Workflow from a button, first set the Workflow to have any trigger. The trigger won't matter too much for this use case but may later if you have other uses such as a schedule.
We will then want to change the event handler for the button so that it triggers the Workflow. This will then allow you to select the Resource as a Workflow, and then find your specific one.
Here is my example below:
Hope this helps! Let me know if you run into any further issues with configuring this triggering.
