Another county judge, this one in Miami-Dade, has ruled the Florida ban on same-sex marriage (and thus the Florida constitution) violates the 14th Amendment of the national constitution. The ruling has been stayed, pending appeal. When the stay is lifted this particular ruling applies only to Miami-Dade County.
There is also a third case in the court system. I don't know if it is before the state Supremes (who would rule on one part of the state constitution being in conflict with another) or before a federal district court. Either way that case affects the entire state.
