I’m trying to achieve something i thought would be extremely easy, but i can’t get it to work!

```auto

for (var i = 0; i<6; i++) {
    if (_root.b1_mc._currentframe == '1') {
        _root.b1_mc.gotoAndStop('_over');
}

```

I want to take the following line:

```auto

    if (_root.b1_mc._currentframe == '1') {

```

and make the ‘b1\_mc’ variable change with the i variable. I thought it would be…

```auto

if (_root.["b" + i]_mc._currentframe == '1') {

```

but that doesn’t work. Any tips on how to make this work?
