Narrative:
I was working FD/clearance delivery. Nid called for P2 clearance for fighter jet X; fighter jet Y; [and] fighter jet Z. I cleared all 3; P2. I then realized what I did because the over flight was at or above FL310 doesn't have to miss panamint; and [also] at or above FL240 over isabella. I told the radar position I messed up with the P2 clearance and I left it up to him to tell nid tower what he wanted since the over flights were owen; saline; [and] panamint at or above FL370 and isabella at or above FL240. He called nid tower back and gave the aircraft P2 with isabella at or below FL230. I thought I heard P2 at or below FL230 so I wrote that on the strip. The radar controller briefs the next controller and told him the P2 was at or below FL230 on the strip. The radar controller lowered the over flight to [the] north to at or above FL240. After another relief; air carrier xa was [at] about nid 045/040 at FL260 and reported a TCAS/RA climb. Air carrier xa climbed to FL266. Fighter jet X climbed to FL260 with fighter jet Y at FL240 below fighter jet X. Air carrier xa had the fighter jet flight in sight. The radar controller did not issue traffic because he was talking to other aircraft in the area. I should have told nid tower myself that the fighter jets were cleared P2 at or below FL230. I left it to the controller to decide what to give to the tower. I should have left the strip alone and let the radar controller write what he told the tower.

Title: E10 Controller described a TCAS RA event apparently resulting from failed intra/inter facility coordination and incomplete strip markings.
