Narrative:

Aircraft X was climbing to 35;000 feet out of 26;000 feet saw traffic at 32;000 feet. Entered interim assigned altitude FL310 in flight data tag and combined up sectors but didn't follow through. I was training and we discussed it. The trainee said she would stop the flight; entered the interim altitude assigned FL310 and I didn't make sure she gave aircraft X the new altitude. By the time we combined sectors and went back to controlling the trainee fell behind with a couple other clearances and didn't have time to turn aircraft X once conflict alert went off.
