EUREEKA!!!!! I figured it out for myself! I had first added the copies and numbered them 120A, 120B, 120C, etc... and I thought that maybe QT didn't recogize the letters. I then tried 120.1, 120.2, 120.3 etc and the new frames still weren't recognized. I then went back and renamed ALL the frames adding zeroes to the ends, so the sequence became 1201, 1202, 1203 etc and... IT WORKED! Sooooooooooooo, QT will not recognize sequentially numbered files that have either a letter or decimal point added on to them.
