If I understand clearly what you mean, you have a state machine (described by the case instruction block) that you want to evolve on the rising edge of the clock signal.

If this is what you want, you must make only one process depending on clock. In this process, you start by 


if rising_edge(clock) then

And inside this if, you put you case instruction block.

Hope this helps.
