Hii,
As you have moved the file from one system to another, there might be possibility that the location which you have chosen in the old system will be different from the location in the new system (e.g while writing the formula in the file (old system) for instance the location of the file is destop & now (new system) the location of the same file will somewhere else rather than destop. Another possiblity may be that the user which was there in old system & in the new system may be different. ( e.g user name in old system xxxx & in new system zzzzz). see this if u still face the problem the let me know.
Thanks
Regards,
Nirik
