I have these array formulas that I want to copy down to other rows
=IF(ISNA(OFFSET($I$115,MATCH($I3&BK$1&$BG3&$BI3,$I $115:$I$417&$AN$115:$AN$417&$BG$115:$BG$417&$BI$11 5:$BI$417,0)-1,18,-1,-1)),0,OFFSET($I$115,MATCH($I3&BK$1&$BG3&$BI3,$I$11 5:$I$417&$AN$115:$AN$417&$BG$115:$BG$417&$BI$115:$ BI$417,0)-1,18,-1,-1))

=IF(ISNA(OFFSET($I$115,MATCH($I3&BK$1,$I$115:$I$48 8&$AN$115:$AN$488,0)-1,7,-1,-1)),0,OFFSET($I$115,MATCH($I3&BK$1,$I$115:$I$488&$ AN$115:$AN$488,0)-1,7,-1,-1))

=IF(ISNA(OFFSET($I$115,MATCH($I3&BK$1,$I$115:$I$48 8&$AN$115:$AN$488,0)-1,35,-1,-1)),0,OFFSET($I$115,MATCH($I3&BK$1,$I$115:$I$488&$ AN$115:$AN$488,0)-1,35,-1,-1))

These three formulas are repeated in the above order between columns BK3
and FQ79 but I need to copy them down to 480. When I copy them one at a time
it seems to copy fine but when I try to select multiple cells I get the
following error messsage and Excel has to close.
"Microsoft Excel for Windows has encountered a problem and needs to close.
We are sorry for the inconvenience."
Does anyone know of a fix or how to rewrite the formulas so it doesn't bomb
out.

Thanks for your help
