[HELP]Blocking buttons

[brocky]

Hello, I need help once again with "blocking buttons". Here is the example of the code.

  
  local button1 = guiCreateButton(13, 54, 140, 29, "Buy Vehicle", false, window1) 
       local button2 = guiCreateButton(158, 55, 77, 28, "Sell Vehicle", false, window1) 
  

Now what I want to know is that, How can i block buttons? example is . If you click "button1" then you can click "button2" else you can't click on "button2" and it will not work unless "button1" was true.

More explanation in simple words is that if you click on "Buy Weapon" button, then you can click on "Sell Vehicle" else you can't click on "Sell Vehicle" if you didn't click "Buy Vehicle" which means you don't have any Vehicle to sell, so thats why buton "Sell Vehicle" is blocked and unblock it when "Buy Vehicle" is true.
