D365 custom workflow issue

I am using a developer VM for platform update 12. I am trying to create a customized workflow for a custom table. For reference, I used the walkthrough on this page: Customization in New Dynamics Ax (Aka AX 7)- Part 6 Custom Workflow. I followed the steps on that post pretty closely.

My problem is when I try to submit something using the workflow that I created. When I click on the workflow button in the menu, I get a button that says submit. When I click this submit button, nothing happens.

I am able to submit items using the workflow on purchase requisitions. When I click that submit button, I get a dialog. However, I noticed that the way the workflow is set up in that form is different from the walkthrough. I have checked all of the workflow parameters that I could find and everything seems to be in order there. I’ve done a full compile of the application and restarted the VM.

Frankly, I am stumped. My gut tells me that I am missing a step or two but I’ll be darned if I can figure it out.
