Is there a simple way to just get rid of the $-sign in the whole database?

I couldn't find anything in the items-table that i could change

Sadly, this is another format that FileMaker doesn't give us programatic control over. You'll want to enter layout mode, select the number fields in question, and edit the number format to use a new currency symbol, or none.

Ok, thanks

I really do like filemaker, but sometimes I think it lacks some functionality.

But I suppose it's not that many layouts to go through

Agree with you on both points.
