Hi Dana,
here's a somewhat cleaned up version of your vi...
Rule of thumb:
Whenever you have the static code in loops (or in each case of a case structure) put the code outside of the structure - as I have done for your 12-case-structure...
Next step: replace the case structure with an array containing 12 strings and use an index array function to get the correct string...
Best regards,
GerdW
