Hi @lakshman and thank you for your reply.
I have a few files, one of them is indeed Excel. The trouble is that i need the select file dialog at runtime, not during development .
I saw that there is an option to select ‘Ask when run’, but that just brings up an input text dialog, which is not helpful for the end user.
Result when run:
I could make a workaround where i have the user have all the files needed(3 files,different formats) in the same folder and have the automation figure out which file is which, but I just thought it easier to just have them select them, like you can in classic Studio using Select File, or a Custom Form.
