Unable to create a dynamic select tool app

[terrellchong]

Hi all

I hope this post finds you safe and well. I am stuck on what appears to be a rather straightforward task, but I've yet to find a solution that works for non-Alteryx personnel.

My objective is to formulate a reliable select tool that can automatically load data from a predefined yxdb source. Furthermore, this tool should be able to eliminate unnecessary columns to provide a more focused, clean dataset for users.

More specifically, suppose the input contains “Field1” and “Field2”. The tool I am trying to build should be able to select only “Field1” leaving behind "Field2".

Why does my select tool look different? See attached snipits  It should look like the normal way where I can see all the columns etc. but I don't.  How can I fix this?  Can anyone please advise?
