If else problem

1

I am having problems with this if else statement.

I have a variable (frame number 30) passing into my swf from another swf. This I know is working correctly.

on (release) { getURL("http://www.website.com/land.html?stateVar=30"); }

I am directing the swf to start on different frame numbers depending on the variable, this is working.

But when I place this code:

if(stateVar==30){
gotoAndPlay(30);
}
else{
stop();
}

I have also tried this:

if(stateVar=="30"){
gotoAndPlay(30);
}
else{
stop();
}

(in case it was a string vs number issue.)

it just stops - it does not go to frame 30.

I need this because I need the file to stay on frame 1 if no variable is passed in.

Am I doing something obvious wrong?
Is there a better way to do this?

Thanks in advance
