Dave, the reason why I use the worksheet calculate event is because it
has to go automaticly!
I don't understand your question... What do I have to fill in by X??
I don't have so much experience with excel macro/code's.

This sheet is linked to another sheet, This sheet has to fill in
automaticly and is locked to change.
Do I have to fill in a new macro, or can I change something in it?

Thanx for your reply.
