Using the Radio buttons within an app to update a formula value

[danettedavis]

I am attempting to use the radio buttons within an app to feed the name of the selected radio button into the value in the formula tool, only my values are not updating to the selected option. I've included a screenshot of how I have it set up and the workflow.  The formula is simply adding a tag to the file as an identifier.  Any help would be greatly appreciated!

You should be using a dropdown for this - not radio buttons. You would really use radio buttons to control optionality of other interface tools - or workflow container enabling/disabling (or detour flows) - for a simple binary selection - use a drop down.

If you need to use Radio buttons your formula is if [#1] then '"Kitc"' else '"Otta"' endif
