Sorry for the late response to your reply post. Unfortunately I had to deal with yet more adware and malware that slipped through.

Thankyou for the help. I had tried that combination of SEROUT/SERIN but it seems that my original IF-THEN statement was the problem here.
IF B0 = B1 or B0 = B2 THEN LED2

After truncating it to IF B0 = B1 THEN LED2 and starting again from the very beginning things began working for me. It was good to get your changes done and be using something that works.

My TRIS and PORT setup was originally like you advised but I must have misread a post and I changed it. It's back to how it should be now.

I haven't used SELECT CASE or the flow control pin before so I'll read up on them.

Thankyou,

Rubicon.
