Hi all,
I'm trying to create a script that will buffer a line. I'm going to place this in a custom toolbox that I made up.
I have the beginning of a script, and when I chose the input when I created it, the dialog won't allow me to pick a data file. I would like to choose a .gdb (or a shapefile) line and create a buffer. What am I missing?
I've attached a screenshot of the dialog.

Thanks for any help.
