VLOOKUP problem

I'm using VLOOKUP to create a Cross Reference tool. CR is my "anchor" page that I'm attempting to tie the remaining worksheets WIT,TEC,COP back to the CR worksheet. I'm able to get VLOOKUP to work on the CR worksheet in columns H & I but unable to get the VLOOKUP to work in column J. The VLOOKUP function is entered but it does not return a value that I know exists in worksheet COP.

Would really appreciate someone letting me know what the problem is, thank you.
