grouping multiple buttons

[tzvi]

Hello, every body .
I'm trying to group multiple buttons via script but unsuccessful
on command
repeat for each line ml in fld "abc_"
    put the name of button ml && "and "&&space into mVar
end repeat
group mVar -- problem with var doesn't get the value instead gets the 
object itself . Below is the message.
set the backgroundBehavior of last group to true
end command
      	executing at 5:31:14 PM
Type	Chunk: error in object expression
Object	kiosk
Line	group vSelectedButton
Hint	button "Appetizers" and  button "Beverages" and  button 
"Breakfast" and  button "Dessert" and  button "Main Dish" and  button 
"Side Dishes" and  button "Soup"
Thanks.
