Changing Button Sizes to fit divergent devices

Getting Started Newbie Questions
1

Hello all, a newbee to lua, so sorry for being stupid about this. 

I currently have this widget set up. But the buttonOne is too small for the iPhone4 and 5 , any help is appreciated 

I tried an if statement using this but without avail , keeps crashing 

–[[if display.contentHeight == 480 then

    buttonOne.pixelWidth = 60

    buttonOne.pixelHeight = 50

    end]]

local buttonOne = widget.newButton{

width = 60,

height = 50,

left = halfW,

top = screenH/2,

defaultFile = “ButtonImages/One.png”,

overFile = “ButtonImages/OneOverFile.png”,

onEvent = onButtonOneRelease, – event listener function

}

You need to have dynamic scaling set up in your config.lua

See the following blog post for some advice:

BTW.

The reason you get a crash in your if-statement is because you’re trying to access an object that doesn’t exist.

buttonOne is created *after* the if-statement.

Okay, got it seen that and fixed the issue, thank you for your help
