I'm sorry, I can't keep up with you here.

Did the Select-case version not work? Is that the reason why you're now using IF and ELSEIF? And did keeping track of the previous state thru the OldState variable not work? Or why did you skip that.

If I got the sequence wrong did you try to correct it and see if the aproach I took would work or not or did you just abandon that idea because I had the reverese sequence wrong?

If the only thing controling the sequence of the commutation is the desired direction then there's no reason to keep track of the previous state because then it doesn't matter.
