How do I set text to add 1 using a for loop?

I'm adding some voucher codes into my game and I need each code to be different. To do this I know I would need to use a for loop or for each but I've never used either of them before, so have no clue.

So far, I've set the text to 'PRZ-0001' when a particular button is clicked but I need to get the voucher code number to increase by one for each click. Therefore, the second click would set the text to 'PRZ-0002', the third click would set the text to 'PRZ-0003' and so on.

Do I need to use a for loop or for each? Do I need to use a number instance variable on the text object? What events and actions would I need to use to get this to work?

You could set a variable on the object and add 1 to it on each click and set the text to "PRZ-000"&var but you may come across an issue when it reaches 10 if PRZ-00010 is not acceptable and should be PRZ-0010 you may need other logic to define this.

It worked! Thanks so much guys - really appreciate it! :)

Your string will be: "PRZ-" & zeropad(counter, 4)

Then you can add to counter 1 by 1.

Oh, nice!
