All I need to have happen is when the user selects #1 and presses enter, then the value of what 1 corresponds to in the background gets passed to a -switch on the final command in the script.

Example:

Main Menu:
1 - Red
2 - Green
3 - White

When the user selects option 2 - green, I need the script to pass a reference value of what the user selects to an actual value that the command can interperet.

So in this example, instead of having the user know the color code of green in html (ie. #123456) he can just select green, but the script will pass #123456 to the actual switch in the command to be executed.
