I've created a hidden field under the Form Options tab named isComplete. This is updated via an javascript jQuery Ajax call to be 'True' or 'False' based on information entered and passed to the Ajax call.

I would like to use the Show Element feature on the submit button based on the value of isComplete, but the hidden field does not show up under If: [Choose Form Element].

I guess I could just enable/disable the button myself in the same javascript function that makes the Ajax call, but I would prefer to use the Show Element if possible.

Not totally clear in what your after and where your looking to make it appear. Are you having trouble getting the hidden field to show on the confirmation?

Sounds like you're expecting to make the hidden field show on the web page when a certain choice is made, but that's not going to happen. "Hidden Field" is only for the results page and nothing more. Some people use this to track down what website a specific form reply came from so they know what websites are working well and getting good traffic and response and which ones aren't getting used much. If you're wanting something to show up to the user, you'll need to create a normal element for that rather than a Hidden one.

No, it's not the hidden field I want to display. The hidden field was just a place for my Ajax call to update with a True/False.

What I was trying to do was use the hidden field in the If: [Choose Form Element] for the Submit button so that the user could only click on it when the hidden field was True.

You'll need to alter the html to accomplish this.

Yea, That is what I ended up doing.

The problem I am altering the HTML after exporting (manual server setup).
This means I have to keep very detailed and careful notes on all my 'edits' and then I have to redo the edits whenever I make a change in Web Form Builder and have to export again.

Is there a better way?

I use the html element on a few of my custom alterations. It cuts down on some of that redo stuff.
