Basically I want this to give the options of inputting Part Description and Part Number rather than Part name and serial number. Is that something you can do?
It appears there is a variable called =LOADSTR(-484) which in the report header outputs the text 'Part name'. I don't know how to change this variable though.
I believe LOADSTR loads the string number 484 from the string resources DLL and it is different depending on what language you are running. The string number stays the same though.
Just overwrite it with your own text, make sure you have a backup of the original label (file header).
