checkBoxes within a ScrollPane

programming flash
1

I’m stumped.

I have checkBoxes within a scrollPane on the main stage.
The buttons associated with those checkBoxes are also on the main stage (can’t be withing the scrollPane). But I can’t get the actionscript to work.

Can somone point out what I’ve overlooked, please??

Checkbox for Blue (placed on main stage) work’s fine
Checkbox for Red is the problem one
Instance = the instance name of the scrollPane
Identifier = the Identifier name of the content within the scollPane

button.onRelease=function(){
 
 if (chbox_BLUE.selected) {
  BLUE._visible = true
 } 
 
 if (Instance.Identifier.CheckBox_RED.selected) {
  RED._visible = true 
 } 
}
