Hi.

Here's what you have to do to make it work:


1. In the main timeline on the first frame:

Set Variable: "size" = 2, not "size" = "2".


2. In the button action:


On (Press)

If (size = 1)

Set Property ("/Menu", X Scale) = 10

Set Property ("/Menu", Y Scale) = 10

Set Variable: "size" = 2

End If

Else

Set Property ("/Menu", Y Scale) = 90

Set Property ("/Menu", X Scale) = 90

Set Variable: "size" = 1

End If

End On


You don't need the second If, you should use "Else" since size is either 1

or 2. If is correct too, but unnecessary. Strangely enough, when you assign

a value to a variable, you should use the variable name set to "String

literal", but when you compare it to a number value, you should use the

following syntax: If (size = 2). No quotes around size and around the scale

values. It would be good for Flash to make a difference between string

variables and number variables, like Javascript does (and many other

programming languages), but for the time being it seems we'll have to do

with that.


HTH,

Calin
