I have a checkbox and a 3 radio buttons. I want to create a script that depending if the checkbox is marked or not and the radio button selection a different script is run.

Scripts will only run in a few contexts

Opening a document

Closing a document

Clicking a button

Choosing a script from the script menu.

So, to do what you are asking you must present the checkbox/radio buttons to the user, allow then to make a selection. Then have them click a button that runs a script that decides based on the values in the check boxes /radio buttons to run another script.

spragueg is right about running the script. it either needs to be run manually from the scripts menu or attached to a button. however, pretty much anything can be a button, including the check box. In layout mode, right click it and select specify button... in there you can say what script you want to run.

Remeber that a button or a checkbox is just a field... the value of the box(es) or the radio button is what goes in the field. Thusly you can use the IF/ELSE logic in scriptmaker to use the settings of radio buttons to control the flow of the script.

Hope this helps.
