Confused Scene Change Error

programming flash
1

Hey folks,

I have a problem when linking two scenes together using this code:

3p_bn.onRelease=function(){
gotoAndPlay(“M2”, 1)
}

3p_bn is my button’s instance name
M2 is my scene’s name
1 being the first frame in that scene

Yet when I execute this program I get an error:

Error Scene=M1, layer=Actionscript, frame=1:Line 3: Syntax error.
3p_bn.onRelease=function(){

I dont understand, as I have exactly same code for my back button:

back_bn.onRelease=function(){
gotoAndPlay(“Mainscreen”, 1)
}

Does anyone know what could be the problem?

Thanks in advance
