FOR LOOP hide

[bno]

I am currently making an application that allows users to customise shapes and draw them dynamically, for part of the form process of it i have to let them specify a colour, i am using radio buttons to let the user choose the colour and am attaching them in a for loop. They attach fine but further down my code on a button release i need them to become invisible yet no matter what i try i cant seem to make it happen inside a for loop? can anyone help me please?

- code to attach buttons:

for (var i:Number = 0; i<colourNames.length; i++) {
        this.attachMovie("RadioButton", "lineColour"+i, this.getNextHighestDepth());
        this["lineColour"+i].setLabel(colourNames[i]);
        this["lineColour"+i].setData(colourValues[i]);
        this["lineColour"+i].setGroupName("lineColour");
        this["lineColour"+i]._visible = true;
}
 

- code im using to try and make them invisible:

    second_FormBut.onRelease = function() {
        if (lineColour.getValue() == undefined || fillColour.getValue() == undefined) {
            trace("You need to select both a fill and a line colour");
        } else {
                for (var i:Number = 0; i<colourNames.length; i++) {
                this["lineColour"+i].visible = false;
            }
        }
    };
}
 
 

I know the code works as in the else block i have run a trace statement returning the selected values but have no luck with this.

Any help much appreciated, many thanks. Michael
