Hi ,

I have two Drop downs. I want to Select another Drop down value based on selection in different drop down.

First DD will have choice label:("dev","engg","it") and choice value:(1,2,3)

Second DD choice Label:  ("DevEnv","TestEnv","ProdEnv","Dev2","Dev3"), choice value :(1,2,3,4,5)

Could someone help in giving me a easy solution. I am learning Appian.

Thanks

Faisal
