Auto Check Boxes from Pull Down Selection

[CecilXavier]

I am trying to get a group of check boxes to auto populate when I select an option from a drop down menu. There will be several drop down menu's and each on should affect the check boxes.
Example. 3 check boxes. Check box a b and c. Pull down menu with Choice 1 2 3 4 5 6 etc. If 1 is selected check box a get checked. if 2 is selected the check box a and b are selected. If on drop down has choise 1 selected and another drop down has choice 2 selected then check box a and b will be selected. (Choice 1's a and choice 2's a and b).

Am I being detailed enough? How would I pull this off.

Hi CecilXavier

I don't think you can do calculations with check boxes.
But you can fake it by using a text field with a border around it.
Using Zapf Dingbat 3 will give you a ? (check mark).
You can use nearly the same calculations you used with CHALEV.
Except you will have to find the script for if/and statements, which you might be able to google.
Your problem is that you will have to write it so that no 2 statements are true or that will give you a false output.
What is the reason for doing this?
