Narrative:
Had eastbound traffic off msp to eau at 7000 ft. Had opposite direction traffic initially descending 6000 ft. Once I knew of the 7000 ft traffic; I stopped aircraft Y at 8000 ft and coordination with msp aircraft Y crossing bitlr at 8000 ft. Went back to aircraft Y and told him to cross bitlr at 6000 ft and put 8000 ft in the data block; thought I have aircraft Y cross bitlr at 8000 ft.

Narrative: HAD EBOUND TFC OFF MSP TO EAU AT 7000 FT. HAD OPPOSITE DIRECTION TFC INITIALLY DSNDING 6000 FT. ONCE I KNEW OF THE 7000 FT TFC; I STOPPED ACFT Y AT 8000 FT AND COORD WITH MSP ACFT Y XING BITLR AT 8000 FT. WENT BACK TO ACFT Y AND TOLD HIM TO CROSS BITLR AT 6000 FT AND PUT 8000 FT IN THE DATA BLOCK; THOUGHT I HAVE ACFT Y CROSS BITLR AT 8000 FT.
