Substract values results in string?

smartman63

Hello,

 

I'm having trouble to substract 2 values. The source attributes (ontwerp & rekenk, yellow) are encoded utf. I convert them to 2 new attributes such as "@real32(@Value(rekenk))". (blue) Then I want to substract those numeric real values in "TEST" but that results in a string? (red)

 

Any ideas?

You need to make sure that you are using the arithmetic editor not the text editor

Or simply wrap the whole expression up into a call to @Evaluate():

@Evaluate(@Value(NUM_REKEN)-@Value(NUM_ONTW))
