Entering default values using question formulas
Before you begin
If you have not already opened the Model window and selected
the model you want to work with, do so now.
To enter a default value using a question formula:
- Place your cursor in
the field where you want to enter a default.
- Right-click and choose
List Q-formulas. (You can also enter a calculation in the field and save
it as a question formula. How?
- From the Question Formula
List, select the question formula you want to use and click [OK].
The name of the selected question formula appears in pink in the field.
- Estimating requires
that the question formula calculate a value that is compatible with the
line type. For example, if you are entering a formula to calculate the
default value for a numeric question, Estimating checks to see if the
question formula you choose returns a numeric response and warns you if
it does not.
- When you are finished,
press Enter.
Tips:
- Press ESC
to remove = from the field without
entering a default.
- You can move your hover tip
over the formula name to display the formula calculation.
- If you enter an invalid formula
in the field, a red triangle appears. Move your cursor over it to view
the details of the invalid formula.
- Instead of choosing from
a list of available question formulas, you can create an
to calculate the default. How?
