ActionScript 2.0 :: How To Move Clip In Which Button Resides

Simple bit of code, a loop that attaches a movieclip, which in turn contains a button. Now, when the button triggers an onRollOver, I need to be able to move the clip which the button resides in. I can't get it to work, and I think it's a scope thing; (Where ident_btn is the instance name of the button in the dynamically attached mc):

Code:
for (var i=0; i <= 15; i++) {
identID = "ident" + i;
var tempgrid = grid_mc.attachMovie("ident_proto", identID, grid_mc.getNextHighestDepth());
tempgrid.ident_btn.onRollOver = function() {
// Move the clip this button belongs to
} tempgrid.ident_btn.onRollOut = function() {
// Un move the Clip this buttons belong to
}
