Sorry I should have given more info.

The script takes 2 input arguments, both of which are numbers. The second argument is a time period in seconds so 0 will be an invalid choice.

The first input argument which is the one that CAN be 0 is later used in the script as part of a system command input option (-Dhw:$in1).
