Actionscript Code:
if (_root["playerMC"+2]._x<=newX) {
    _root["playerMC"+2]._x += speed;
}
if (_root["playerMC"+2]._x>=newX) {
    _root["playerMC"+2]._x -= speed;
}
if (_root["playerMC"+2]._y<=newY) {
    _root["playerMC"+2]._y += speed;
}
if (_root["playerMC"+2]._y>=newY) {
    _root["playerMC"+2]._y -= speed;
}
Because I need to add tons of those... but with different ["names"]+2.
