How to avoid error " Not enough system resources to display completely"?

Hi,

I am tired of this error in my workbook "Not enough system resources to display completely". If I click on ok, it disappears and don't create any problem as such.. I have used forms to show some data and many cells in my workbook uses this formula.

Is there any way to avoid this error?? Any excel expert to answer this asap.

Regards,
Anu
