Hi,

I am trying to fill down an array formula through a column of about
2000 cells. Somewhere at the 860th cell, the cell appears blank (no
formula in it) and I cannot keep filling down. The cells pointed to are
not blank (I checked that) and there seems to be no problem with the
formula. Could it be an issue related to memory?
Any help with this would be greatly appreciated,

Thanks very much.
