Use this procedure to evaluate the result of a formula. After you complete the formula property definition and add the property set to objects, you can use the result of the formula in schedule tables and schedule tags.
- Confirm that for each property definition in the formula, the value of the property is:
| retrieved from the object or style. |
| formatted using the property data format defined in the sample value format. |
| inserted into the formula in place of the property definition name and the brackets surrounding it. |
- Evaluate the formula string:
| If the formula string… |
Then… |
|---|
| contains the word “RESULT” |
it is evaluated as a VBScript function, and the value displayed for the property is the result of that evaluation. |
| does not contain the word “RESULT” |
it is evaluated as a mathematical expression. |
Note: Make sure that all property sets used in the formula have been applied to the object or style. Otherwise, a question mark (?) is displayed in the schedule table.
