Wildcard input problem

[wave_wstn]

Hi Alteryx, 

I am using the wildcard to input data of a folder that is all csv files, except its not working. I attached the photo of what the input looks like. I do not know why it is not letting me drag in all the files, even though it worked for another workflow

What happens when you run the workflow? Do you get an error message that you can share?

Thanks
