Okay, so I modified my code to use ArgsContext, but now I'm running into another problem. Whenever I try to use ArgsContext to obtain a value from my parameter list, I get an error stating, "SyntaxError: Invalid character [MsgId: MERR-203252]." I tried loading the variable directly using a windows alert as well, and it seems like I must be receiving some sort of garbage character? There doesn't appear to be any problems with my parameter list file, but I'll attach it just in case. (Saved as .txt since I can't upload .dat)
EDIT: I felt I should note, my column delimiter is tab, not comma. It's a single column file.
