Stored value

If you want the value stored in a custom field to be different from what is displayed in the combo box you can use the following syntax in the Values section:

StoreValue1=DisplayValue1;StoreValue2=DisplayValue2;StoreValue3=DisplayValue3;

The value before the equal sign will be stored. The value after the equal sign is what will be displayed in the combo box (or check boxes), but does not get saved.
