ZLC Supervisor described an incorrect restricted area posting event indicating the present procedure of utilizing two separate forms for posting is confusing and leads to mistakes as reported.

Narrative

The MOS; Military Operations Specialist; received release of restricted area airspace and forwarded it to the area in an incorrect release sheet. In this case R2501 real time changes are written on a 'released at or above' sheet and then given to the area. The MOS incorrectly gave me a 'Hot at or below' worksheet. The R2501 was hot; AOB (at or below) 160 and was posted in the area as being released AOA (at or above) 160. There are 2 separate worksheets for the real time release of military airspace; there is the 'hot at or below' or the 'released at or above'. The problem is that when you are given a worksheet for a specific military airspace we make the assumption that it is on the correct worksheet. I do not expect the R2501 airspace to be posted on a 'hot at or below' worksheet; therefore all I saw was the altitude and posted it as being released AOA160 (R2501 is always posted on a 'released at or above worksheet). I posted the airspace incorrectly; it should have been posted as released AOA 170.There were no airspace deviations in this incident and I did report the incident. There should be only 1 sheet that reflects the status of real time changes; this would avoid the incorrect posting of airspace. Recommendation; for consistency; there should only be 1 worksheet for the release of military airspace. Having 2 separate worksheets allows for human error to incorrectly annotate releases.
