I need help integrating EEPROMEX.h

Perry,

I dont know how to post the file for the modified sketch of this project.

There are several ways to post the file. 

1) you can copy/paste it into your post.

2) you can attach it as a separate file.

note: to paste, sometimes you have to hold the "Control" key when you right-click the mouse.

note: to attach a separate file you have to use the "advanced editor" which can be selected

in the upper-right part of the posting window, then look at the bottom of the window for "Attach file".
