- | In numeric calculation fields, Variable Names are used without the `%` that are used in text token fields. Do not try to use tokens (like `%Variable%MyVar%`) in numeric calculation fields, just use MyVar by itself. The variable must contain a valid numeric value, or an expression (v8+) that evaluates to a valid numeric value. So for example, if MyVar contains a text value of `2*3`, then the calculation `4*MyVar` will return 24. | + | In numeric calculation fields, Variable Names are used without the `%` that are used in text token fields.
