I am revising my OBDII tool timer and wanted to add a "None" menu item for the selection of PID parameters to pool. However, the string array will have blank lines if "None" is selected. I want to have the timer by-pass any blank line values and just cycle sending only the selected PID parameters to the bluetooth OBDII adapter. I have tried several things but depending on where "None" is selected and where affect whether the timer works properly or not.

Does anyone have any suggestions? I would prefer not to have Ruby solutions.
