User-defined variables are broken into two categories: String and Numeric. Using either type of variable is pretty straightforward. The following table explains when you would use a string vs a numeric variable:
| String | Numeric | |
|---|---|---|
| Assign a literal value | TRUE | 27 |
| Assign the value of another variable | {LeftVM} | NewRate |
| Use in an expression | LeftVM="TRUE" | TOTAL>0 |
| Variable Substitution | Call from {ANI} | N/A |
| Calculations | N/A | HourlyRate*1,25+50 |
