Thanks Ropu for the clarification. I figured it might not hurt to put the two files in both locations, so I as far as I can tell I have resolved that issue.
I am still having problems getting UPS Ground to show up in my cart once the GC button is clicked. The only shipping options that show up are 1DM, 1DML and XPD even though they show as commented out in mcshipping. I deleted line 117 so UPS Ground was NOT commented out, but as a novice, perhaps that was the wrong move. Perhaps you could give me some guidance here?
