so in the open position my the string is in tune but at the second octave (12th fret) it is sharp and when I lower or raise it to make it in tune then the open is sharp how can I fix this?
When you say 'lower or raise it', are you referring to raising or lowering the whole bridge?

EDIT: what kind of guitar is this on?
PRS SE Custom 24
Jackson DKA7
Gibson Explorer
MESA/Boogie Express 5:25

Dunlop Cry Baby Classic
VOX Joe Satriani Ice 9 OD Pedal

Moving on.....
Your not adjusting the intonation man, your adjusting the action. Read this, and ask any questions there,
