you need to declare your vars at the top of your method or procedure.

eg:

Good:
(method (foo)
   (var a)
   Print("Hello")
   Print("There")
)

Bad:
(method (foo)
   Print("Hello")  
   (var a)
   Print("There")
)

Thanks Brian.

Now I got "out bracket" message.

Here my codes:

(instance RoomScript of Script
 (properties)
 (method (handleEvent pEvent)
  (super:handleEvent(pEvent))

  /*****************************************
   * Handle the possible said phrases here *
   *****************************************/
  (if(Said('look'))
   (method (foo)
    (var button)
    //= button
     Print("You are in an empty room")
     Print(
     "Do you want to click Yes or No?"
     #title "Click What?"
     #font LARGE_FONT
     #icon 0 0 0
     #button " Yes " 1
     #button " No " 0
    )
    (if(== button 1)
     Print("You clicked YES")
     )(else
     Print("You clicked NO")
      )
     )
    )
   )
  )
 )
)

the "  (method (foo)" was just an example of using vars. It's not to be in your code.

Do it like this:

(method (handleEvent pEvent)    
  // right after your method declaration
  (var button)

  (super:handleEvent(pEvent))

  /*****************************************
  * Handle the possible said phrases here *
  *****************************************/
  (if(Said('look'))

    //= button

    Print("You are in an empty room")
    Print(
    "Do you want to click Yes or No?"
    #title "Click What?"
    #font LARGE_FONT
    #icon 0 0 0
    #button " Yes " 1
    #button " No " 0
    )
    (if(== button 1)
    Print("You clicked YES")
    )(else
    Print("You clicked NO")
      )
    )
    )
)

Thanks Brian.

I didn't get an error from compiler this time.

Either I click on yes and no buttons, i got "you clicked yes".

Here the code:

(instance RoomScript of Script
 (properties)
(method (handleEvent pEvent)
  // right after your method declaration
  (var button)

  (super:handleEvent(pEvent))

  /*****************************************
  * Handle the possible said phrases here *
  *****************************************/
  (if(Said('look'))

    == button

    Print("You are in an empty room")
    Print(
    "Do you want to click Yes or No?"
    #title "Click What?"
    #font LARGE_FONT
    #icon 0 0 0
    #button " Yes " 1
    #button " No " 0
    )
    (if(== button 1)
     Print("You clicked YES")
    )(else
     Print("You clicked NO")
      )
    )
    )
)

Now here, you just want to assign 'button' to the last Print value, e.g.:

= button    Print(
    "Do you want to click Yes or No?"
    #title "Click What?"
.
.
.
