need help with a formule

[sebasjuh]

I am working with excel (one of the first time I use excel ) but
have a problem.

I have this formula:
=SOM(Q8*Instellingen!B16*Instellingen!Q3)

But when you leave the field blank in Q8, you see in the field wher
this formula is a -

How do I change the formula to see nothing in that field???

(i hope you guys understand it a little bit

Try something like

=IF(Q8="","",SUM(Q8*Insetllingen!B16*Instellingen!Q3))

I tried this code
=IF(Q8="","",SUM(Q8*Instellingen!B16*Instellingen!Q3))

But I get a error and it says that the formula is not good.

do you have a regional setting that uses the semi colon ( as the list
separator rather than the comma. If so, it should be:

=IF(Q8="";"";SOM(Q8*Instellingen!B16*Instellingen!Q3))

or just

=IF(Q8="";"";Q8*Instellingen!B16*Instellingen!Q3)
