You've wired a constant 'Wait For Data' to the case selector, so it will always execute the same case.  You want to add a shift register to the while loop, move the 'Wait For Data' constant outside the loop, and wire the unconnected output of the case structure to the right-shift register terminal.

Hi Paul

I have changed the code as you suggested and it now works however I have a problem because it exits the while loop and closes my (CLOSE LJM Vi) which stops it working properly how can I resolve this?

The only way it exits the while loop is if you hit the stop button.

One problem I do see is that you have a blue wire that runs through the missing subVI's.  But where that wire exits the case structure, you have it set for "Use Default if Unwired" on that case tunnel.  That means you risk losing the data in the wire when that case structure ends.  You should uncheck that tunnel setting, and make sure it is wired through every case, even those that don't use it.
