Polypainting: Tx>Col Greyed Out

Hi all,
I was just curious if anyone knew what to do after you’ve finished polypainting and the tx>Col button is greyed out. I’m reading Scott Spencer’s book and it says this is the button to turn the polypaint into a texture but I am a little stumped now that I can’t press the button to proceed. Thanks in advance!

never mind. Got it to work. Thanks!
