Cell not refresh probably.....

[Guest]

Hi,

I'm running Office 2003 SP1.

I got a range of cells which refers to a function in a module. I'm getting
the following error when pointing to the exclaimation mark:
"A value used in the formula is of the wrong data type."
However, when I select one of this cell, and go into edit mode (I usually
press F2), then press Enter without modifying anything, the error
disappear, and I get a value from the function.
My problem is that I have a range(AE21:AI136) which pretty much used the
same formula, I can't expect user to go through each cell and fix it like the
way I had, so does anyone know how can I fix this?

Regards
Augustus

Augustus,

What happens if you press F9 or use application.calculatefull ?
It would help if you could show the function.

Tim.

I tried both F9 and application.calculatefull, only application.calculatefull
work.
The code is as follow, I hope it is not too long:

What is "LookUpExtensionTable" ?

If this another function then your first function may not calculate
automatically if anything changes which would affect the output of
LookUpExtensionTable.

AFAIK a custom function only recalculates when one of its inputs
changes.
