Drop down for dynamic selection not working even with list populating

[Ethang482]

Hello - I'm currently working on a project that I need a dynamic drop down for. Currently I have this set up using the 'Drop Down' and 'Action' tool for my workflow where I have created the list of values I want to select from. These locations populate in my 'Run as an Analytic App' questions but when I choose a location --> finish its showing "No Output Files." 

Is there something I'm missing?

Are you using a part of your workflow to populate the dropdown or are you manually setting those values?  Remember that they need to be formatted as NAME:VALUE.  If you don't have it in that format it will not appear to be working.

Otherwise, can you elaborate more on your need?  -Jay

Yes, currently using location names that are a part of my workflow to populate via the Summarize ---> Transpose Tools to create my list.

I have my dropdown selection tool to show all field types to then into my action tool where I have the Update Value (Default) Operand - value= Name.

This all flows back into the main workflow with a filer tool to search by the district (Location)

If you're going to do that, you need to create a chained application.  The app won't run anything until after the user prompts are entered, so by the time you need them, they don't exist yet.  So, a chained app will run the first part: to populate the drop list, then the second app uses it and runs the rest.

That makes sense. Is there an alternative to keep it on just one application?

Will the list change often?  If not, just put it into a text input or manually populate it?  My guess, though, is that you need it more dynamic?  -Jay
