Scrolling image left and right


Here is a project where in there are product image which should be scrolling left and right with mouse movement and on cilck it will get linked to their respective pages. Attached is my file where in the code is taken from flashkit. I have edited the code to some extend. But there is 1 probs. I have applied masking to the image strip. On repeat of the secound strip the masking is overlapping and the complete strip can be seen WHICH IS NOT CORRECT.

Attached is the file for your refernce. please let me knw ASAP about the query
