Illegal Characters

The constants in the formulas are entered as arbitrary real numbers, and the mathematical and logical operations are performed using the allowed operators. Any character that is not explicitly allowed is therefore illegal.

For a list of allowed characters, see chapter Formulas.

The formula test expects that only allowed characters are used in a formula. If this condition is not met, the formula test returns an error:

Characters that are used in the formula but are not allowed are also displayed. Formula testing puts us on the problematic character, to make it easier to correct the formula. (If there are more than one such characters in a formula, it puts us on the first illegal character found.)
There are two possible solutions:
1. Deleting an illegal character if it is entered accidentally.
2. Correcting the entered formula accordingly, using the allowed characters.

To Example 1:
#QUANTITY# *75

*75! |
To Example 2:
*75/100
#QUANTITY# *0.75
#QUANTITY# *0.75
PRICE*1,2
|
*75%
#QUANTITY# x 0,75
QUANTITY *0,75
#PRICE#*1,2
