Is there something wrong with the following code?

myFilename = MGR_SHORT_NAME + Sheets("Inputs").Range("E11").Value + "SUMPRF"
+ ".L00"

It keeps bombing out when it goes to find this file, because the actual
file, of course, was named so that it has the MGR_short_name in the front
part of its name, but the macro doesn't seem to recognize it, i.e., when it
responds that it cannot find the file, the name it says it is looking for,
does not have this first part.

Thanks,
Grace
