[Contribution] Option Types v2 in General Add-Ons Support Posted January 19, 2010 I have this issue and have looked and relooked the shopping cart class. Anyone want to take a stab at it? You just proved some of my earlier comments: 1) Problems occur when merging contributions 2) Problems occur by not merging the files correctly 3) You should use a 3-way compare program to compare: Original osC file, Edited file, File to Add (You would have easily picked up the mistake(s) you made) Don't know if this will solve the problem, but below the line: //BOF - Zappo - Option Types v2 - Because of Text and Upload options, $option AND $value don't have to be numeric! You should comment out the entire check! (reason: exactly like the comment says) This stood out when I scrolled down the page, and I did not check for any other mistakes or faults... I recommend using kDiff3 when merging files. That program saved me a lot of headaches!
