Dears,
I'm looking for a way to include SUM for a non existent sheet so I can avoid the #Ref error. This is for Excel 2010.
Something along the lines of =IF(ISREF(INDIRECT("'7999'!E2"));INDIRECT("'7999'!E2");""); but with SUM added for E:E for a specific sheet.
How would I go on about this?
Thanks and Regards.
