Using a combo box value as a condition?

This seems like it should be obvious, but I'm not seeing it: If I want to take an action based on a particular value selected in a combo box, how is that done? When I select the combo box as a condition, the closest I see to this is the alterable value that can be compared to a fixed ore retrieved value.

For example, let's say I have values 1-12 in a pulldown list, and I want one action if 6 is selected, another if 5 is selected, etc.

Thanks.

Click on new condition.
Click on the Special icon.
Select Compare two general values.
Click the 'Retrieve data from an object' button.
Now you'll see that you have alot more choices to choose from the combo box :)

Thanks. That was what I needed.
