fix WHAT exactly?

you have / draw 4 pages
and want jump between them by mouse click on hardcoded buttons?

better error description please

Hello

Is this a homework or academic assignment?

Is it a new topic or related to your last topic? They look similar.

A clear statement of the problem helps.
Add some comments to your code.

Consider drawing a “state diagram”:
State Diagram
I use state diagrams and flowcharts for my more complex code.

Hint to get you started:
Try putting flag = 0; at the end of if statements in the main loop; try one at a time and observe.

That is it for now…

I remarked in his last thread that arrays would be the way to go

But he‘s doing a good job!

kll · November 12, 2019, 12:16pm

but even only button variables and a over function would be a big advancement, see
Background(image) not working - #74 by Chrisir ,

here is a working version. There were a lot of small things to fix.

(as I said: Arrays)
