Array formula will not copy any further- Help ASAP!

[Guest]

I have an array function that brings in the margins for pricing from another
sheet in the workbook. Currently, it has about 13,000 part numbers on it.
When I copy the formula normall, I use the drag box on the cells. Right now,
I am stuck on row 11,000 because the formula will no longer copy any further-
it just leaves the cells blank and bounces back to where I started to copy.
How can I fix this? I've tried everything from adding new cells to checking
the formatting of the cells. Any help would be greatly appreciated!

numbers on it. . . .

The other worksheet has 13,000 part numbers on it?

OK, have you tried to copy the cell containing the presumably single cell
array formula, then select the range into which you would have filled it,
then paste into that range?
