Newbie Stepper Motor/Display was working now 1.6.7 has errors won't compile

My project is to move a stepper motor to control a variable capacitor and feedback info to an LCD.

I had just the basic multiple button switches to single pin working and had added some stepper motor movement to button 1 just a week ago. Today the previously working project fails. Updates to IDE impacted?

Assistance gratefully received.

Thanks

Nigel

Please modify your post and use the code button </> so your code looks like this and is easy to copy to a text editor. See How to use the Forum Your code is too long to study quickly without copying to a text editor.

If this was my problem I would just use the version of the IDE that did not cause errors. You can easily have multiple versions of the IDE on your PC - it is just a Java program.
