Color Match Option Grayed Out HELP

[jskwarek]

I'm trying to do a quick edit and rematching color, I've done a selection on one image and have gone to another image and selected the color I'd like to match off of but when I go to ADJUSTMENTS>COLOR MATCH the "color match" option is grayed you. Any ideas, what am I missing?

TIA,
Jason

Got it! Mode was CMYK not RGB.
