Narrative:

I was the dispatcher on an aircraft with multiple MEL's. These MEL's pertain to both the right fuel used indicators. Also, the left main tank quantity system was deferred. These MEL's were added at different times and there was question as to how the MEL book was worded. After conferring with maintenance control, it was determined that since the MEL's were on the opposite side of the aircraft, all parties agreed that this aircraft could be dispatched. Later, we found that we could not operate that flight with both MEL's and cleared the one.
