Retrieving info from a dynamically created array

“oneColourArray” is an array that is filled with numbers from an xml file. I also have an array called “twoColourArray”. So I need a way to switch between the two.

oneColourArray[0][0] should equal “8”. Ive tried using toString(), Number, parseInt, but nothing is working. Please help

var myvar:String
myvar = “one”

var myArrayInfo:Number
[FONT=Tahoma]myArrayInfo[/FONT][FONT=Tahoma] = [(myvar + “ColourArray[0][0]”)]

trace [/FONT]FONT=Tahoma[/FONT]
