No, you don't really need to use labels.

Cause you just do like, if whatever = true then

So, you don't really need any labels or goto's, but either way I don't know how.

Sorry :(

That's because System.usbDiskModeActivat e() turn on the usb, it doesn't return a value. You also don't need else there. Also leave out the false, unless you don't want your picture to have transparency at the parts it had transparency in the .png.
Here, try this:

Code:

---

usbStatus;

function usbON()
        System.usbDiskModeActivate()
        usbStatus = true
end

function usbOFF()
        System.usbDiskModeDeactivate()
        usbStatus = false
end

if UsbStatus then
        screen.blit(460, 260, usb)
end

ignore the strange spaces in the middle of the usbDiskModeActivate and usbDiskModeDeactivate, it's just something the forum does.

anybody know how i can create labels?

like:
lbl b
then later:
goto b

---

Labels are pointless since there are loops and functions.

Exactly what I said ^ :)

well then how do i make a loop?

while true do

ohkay?
i just dont see how that will make the program loop over and over again.
well i have a problem where the 'end' code is executed before i can press a button.... i know that you have seen the script.
