Selecting lowest counter and sending binary output

Part one: I have three counters. I need code that selects the lowest counter and increments this counter after it sends a command to the corresponding digital output (to close a contact).
Part two: I will be issued a point (1,2, or 3). This number will determine how many counters I need to select and how many digital outputs need to assert (to close a contact)
Part three: This issued point will change. Once this point drops down I need to send a command to the corresponding digital output (to open a contact)


I am using Subnet Solutions SSnet Explorer. This interface only has basic logic functions and math functions. I am trying to put together nested if statements but I am stuck
