I am having trouble getting values after I use a modal New Window Box. 
If I run the example from the JMP 9 Scripting Guide:
New Window("Set a Value",<<Modal, 
     TextBox("Set this Value"),
     variablebox = Number Edit Box(42),
     Button Box("OK"),
     Button Box("Cancel")
);
variablebox<<get;
I get this error: "Send Expects Scriptable Object in access or evaluation of 'Send', variablebox<<get
On the other hand: 
When I run just the code 
variablebox = Number Edit Box(42);
variablebox<<get;
I get:
42
Anyone know what I've done wrong here? I can't seem to make  "get" retrieve variables from any of the modal windows I've tried. 
Thank you!
