How to add more conditions to a If Then... Ill explain... hELP

Ok here is the problem… I have this code:
[AS]
onClipEvent (enterFrame) {
if (this.hitTest(_root._xmouse, _root._ymouse, true)) {
} else {
this.gotoAndStop(1);
_root.SUB.gotoAndStop(1);
}
}
[/AS]
The thing is I want to make it so it checks to see if my mouse is over the button (which the code i have already does) and ALSO checks to make sure a movieclip is on frame one.

So it would be something like:
[AS]
onClipEvent (enterFrame) {
if (this.hitTest(_root._xmouse, _root._ymouse, true) and MovieClip is on Frame 1) {
} else {
this.gotoAndStop(1);
_root.SUB.gotoAndStop(1);
}
}
[/AS]
of course that isn’t proper action script but i am tyring to get my question across… THank you very much.

[AS]
onClipEvent(enterFrame)
{
if (this.hitTest(_root._xmouse, _root._ymouse, true) && clip_mc._currentframe == 1)
{
//some code
}
else
{
this.gotoAndStop(1);
_root.SUB.gotoAndStop(1);
}
}
[/AS]

Thank U So Much!
