Search and replace Formules

[HenkN]

I am trying to search and replace a part of a formule, but I am doing something wrong probably, because the program does not replace it.

I have use the formule =If(B3=0;0;B3/$AB3) alot.
The last part $AB has to become $AF.
A search and replace won't work. I already checked if the option "Formules" was selected. I am using OOo 1.1.3.

I hope someone can help me out!

Already tnx!

Try finding \AB and check the Regular Expressions box.
