Hurtige,

Generally, you need to wrap at least one indirect in the iserror function to trap the error..

Perhaps:

=IF(ISERROR(INDIRECT("'[Kreditor mappe
"&B9&".xls]Løndebitorer'!$L:$L")),SUM(INDIRECT("'[Kreditor mappe
"&B9&".xls]Ferieval.'!$L$1:$L$40")),SUM(INDIRECT("'[Kreditor mappe
"&B9&".xls]Løndebitorer'!$L:$L")))

Hi everybody

Im working on a worksheet where i wanna check cells in two other types
of work sheets but but only one of the exists for each number.

Ive made this cell: "=OR(SUM(INDIRECT("'[Kreditor mappe
"&B9&".xls]Løndebitorer'!$L:$L"))+SUM(INDIRECT("'[Kreditor mappe
"&B9&".xls]Ferieval.'!$L$1:$L$40"))0;SUM(INDIRECT("'[Debitor mappe
"&B9&".xls]Løndebitorer'!$L:$L"))+SUM(INDIRECT("'[Debitor mappe
"&B9&".xls]Ferieval.'!$L$1:$L$40"))0)" but of course i get #REF!
because one of the files are missing, i want to know how i can set
#REF!=0 and even if i didnt have that problem i would still only get a
true or false answer. And i want a 1 or 0 answer. I cant figure out how
to get "=if()" to recognize if the "=or()" result is right.

I really hope theres a hardcore excel user out there that can help me
