Hello I try to make IF-statement that do this:

IF( GETWORKDAYS(Installningar!$A$2;(DATE(200&(LEFT(N2;1));1;-5)+(MID(N2;2;2)*7)+RIGHT(N2;1))-1)="#VALUE!", not a value, GETWORKDAYS(Inställningar!$A$2;(DATE(200&(LEFT(N2;1));1;-5)+(MID(N2;2;2)*7)+RIGHT(N2;1))-1))
but it don't work.

Can anyone here see what is missing?

In the cell Installningar A2 it says : 2005-10-04

Please help
