Sorry Acetronics, it made perfect sense to me when I wrote it Now that I have re-read it I can see that it doesn't make any sense at all.

What I'm strugling with is the keypad/membrane switch, though I can find lots of examples of interfacing a numeric keypad. If I was using a 3x4 KP/MS I could name the buttons and variables

btn0.......btn7, btnre-set, btndisplay

var num0.......num7

The part I'm having difficulty with is the coding to scan the buttons and add a count to the appropriate var i.e.

WHILE btndiaplay = NO

SCAN btns

IF any btn is pressed and 1 to that btn's var

I hope this makes more sense and appreciate anyone offering help


P.s. a 'FULL PROJECT READY TO SWITCH ON' would be nice, if anyone has one
