Array for going through checkboxes (Newby question)

Hi all,

I am trying to get a simple piece of code to work but it gives me an error

--Unknown property: "Checked" in "chk0"

I want the script to add the number of each checked checkbox to an empty array (see line 28)

I think my issue is that chk0 is a string in my script and thus I get the error.
This should be a simple error on my side but I am not sure how to fix it.

rollout Test "Test" width:300 height:803  ( --start of Rollout Exporter
	button btn_test "Test" pos:[18,14] width:116 height:60 toolTip:"If 'overwrite name' option is not used; obj name of currently selected obj will be used"

You're trying to access a

You're trying to access a parameter of a string value (i.e. of the name of the checkbox control), not the control itself. Also note that there's rollout.controls array that will give you the list of all the controls of the rollout. Something like this should get you started (untested but in the worst case you'll have something to dissect and analyze):


Array_chkboxes = for c in test.controls where isKindOf c CheckBoxControl and c.checked collect
