Number fields formatting as currency when inserted in text
I have encountered a little problem that sometimes when I include a number field in a text string - e.g. when I'm writing a letter for printing and I'm using <<Field>> to merge, sometimes, if the field refers to a number, it automatically formats as 403kr. (I'm scandinavian, and the kr. refers to our currency, kroners).
But since it's not all my numbers that are supposed to be currency, It's pretty annoying - anyone knows how to change this?
