Many Thanks, This is great.
Hi everyone This is the perfect answer if any one have same trouble as I found before. Thank you Planteg
the reason is that GetWorkDays() is not a built-in function but a Custom Function:
You need to copy it to your other file. In that other file:
- do File > Manage > Custom Functions
- click on import
- pick the Tasks file
- select GetWorkDays
- and import
If you follow my link, you'll see how Phil suggests the calculation should you not have FileMaker Pro Advanced.
Thank you Beverly, I have save that in to disk It will be useful later.
