Hi
I have an Excel file with VBA function
The problem is after a while of working with this file, the VBA function "get tired" , that mean they not refresh or return zero or value instead of valid number.
some pepole told me it's becouse the RAM memory is full (even it's nice strong PC).
Does someone know how to Handle this problem ? (F9 doesn't help)
Is there any way to clear the memory that those Function take ?

Thank's for any help!
