Narrative:
The problem arose when I decided to descend aircraft #1 to FL240 and climb aircraft #2 to FL390, when they were on conflicting paths. Aircraft #1 needed to cross lvz at FL190. After giving the 2 clrncs, I determined that a conflict would occur. I turned aircraft #1 to a 080 degree heading. I turned aircraft #2 approximately 30 degrees left. Before where I believed I would lose separation, I asked aircraft #1 to verify leaving FL265 which was replied as affirmative. I asked aircraft #2 to verify leaving FL275 and heard 'yeah.' after hearing yeah, I tried to enter reports. Upon reflection, I don't know if yeah was an appropriate report in this instance.

Title: RPTR DID NOT ENSURE STANDARD SEPARATION EXISTED BTWN ACFT #1 AND ACFT #2. THIS RESULTED IN AN OPERROR.
Narrative: THE PROB AROSE WHEN I DECIDED TO DSND ACFT #1 TO FL240 AND CLB ACFT #2 TO FL390, WHEN THEY WERE ON CONFLICTING PATHS. ACFT #1 NEEDED TO CROSS LVZ AT FL190. AFTER GIVING THE 2 CLRNCS, I DETERMINED THAT A CONFLICT WOULD OCCUR. I TURNED ACFT #1 TO A 080 DEG HDG. I TURNED ACFT #2 APPROX 30 DEGS L. BEFORE WHERE I BELIEVED I WOULD LOSE SEPARATION, I ASKED ACFT #1 TO VERIFY LEAVING FL265 WHICH WAS REPLIED AS AFFIRMATIVE. I ASKED ACFT #2 TO VERIFY LEAVING FL275 AND HEARD 'YEAH.' AFTER HEARING YEAH, I TRIED TO ENTER RPTS. UPON REFLECTION, I DON'T KNOW IF YEAH WAS AN APPROPRIATE RPT IN THIS INSTANCE.
