Rollover TextField - NOT button - using asfunction?

programming flash
1

I got this:

X25 = "<a href=\"asfunction:myClick\">Show Box</a>";
box._visible=false;
function myClick() {
	box._visible=true;
}

[color=#003366]

Where X25 is the name of a dynamic text field variable (not instance name).[/color]

What I really need is for a rollOver action - you need to physically click the text box for it to work and I need that for another action

Any help much appreciated.

Cheers.
