hey i use to have this code but i wasnt working -
```auto
button_array = ["home", "plans", "terms", "contact"];
for (var i in button_array) {
btn = this[button_array*];
btn.clip = this[button_array*]+"_mc";
btn.onRelease = function() {
_root.fromName = btn.clip;
content_mc.gotoAndPlay(36);
};
}
```
so i forced to change to individual onRelease functions -
```auto
home.onRelease = function() {
_root.fromName = "home_mc"
content_mc.gotoAndPlay(36);
};
plans.onRelease = function() {
_root.fromName = "plans_mc"
content_mc.gotoAndPlay(36);
};
terms.onRelease = function() {
_root.fromName = "terms_mc"
content_mc.gotoAndPlay(36);
};
contact.onRelease = function() {
_root.fromName = "contact_mc"
content_mc.gotoAndPlay(36);
};
```

eze, your for loop isnt proper syntax…
[AS]
for (var i = 0, i \< button\_array.length, i++) {
//statements;
}
[/AS]

yea it is, dunno what its called but that isnt the problem, BTW lostinbeta gave me the first code, well modded mine to that so it is working and it works for the gotoAndPlay part of the function, just not the \_root.fromName varible doesnt seem to be set

whats the var “clip” in btn? and whats btn?
btn should be defined f.e. as a MovieClip (like in btn = new MovieClip()😉 if you want to attach the var clip to it.
Its not like you can grab a varname out of the blue and put another var in it.
Ive experienced the same problem time after time, till i discovered in a case like this that the var clip doesnt really exist at all.
so my solution to your code is this (and this one does work!) :
(make sure you have a movieClip on your stage called “btn\_mc” with a button in it called “btn”)
```auto
button_array = new Array("home", "plans", "terms", "contact");
singleButton = new Array();
for (var i in button_array) {
singleButton* = btn;
singleButton*.btn.clip = button_array*;
singleButton*.btn.clipname = button_array*+"_mc";
//trace(singleButton*.clip);
singleButton*.btn.onRelease = function() {
//_root.fromName = this.clip;
trace(this.clip);
trace(this.clipname);
//content_mc.gotoAndPlay(36);
};
}
```
enjoy, gl =]

My bad, try
```auto
button_array = ["home", "plans", "terms", "contact"];
for (var i in button_array) {
btn = this[button_array*];
btn.i = i;
btn.onRelease = function() {
_root.fromName = button_array[this.i]+"_mc";
content_mc.gotoAndPlay(36);
};
}
```
