Hi,

I have used the following code before in another program, but when I copied it and pasted it on a present program it does not work. Could someone please let me know what I am doing wrong:

local ui = require( "ui" )  
  
-- Handler for edit button  
local edit\_btnRelease = function( event )  
 print("nothing yet");  
end  
 -- display edit button  
  
local edit\_btn = ui.newButton{  
 default = "buttonBlueSmall.png",  
 over = "buttonBlueSmallOver.png",  
 onRelease = edit\_btnRelease,  
 text = "edit",  
 size = 11,  
 emboss=true  
 }  
edit\_btn.x = 200; edit\_btn.y = 250

It gives the following error:

ui.lua and the corresponding images are all in the same place as your main.lua right?

I don’t know, I got around it by using the button method on this tutorial:" Corona SDK 10: Screen Transitioning ", by Dr. Rafael Hernandez at http://www.youtube.com/user/cheetomoskeeto
