How To Make Stopwatch Run Continuously?

I'm looking to have my stopwatch run continuously until "and only until" a command button ("Stop") is clicked. I already have a code and stopwatch in place. I have 5 command buttons: start (starts the timer), call (activates/hyperlinks to another sheet where I have more command buttons and data entry needed/), stop (stops the timer), reset (resets the timer), and record (stamps the elapsed time on the sheet1).

They work great BUT the problem is, when the cell is touched (i.e. when you type a character or double click on any cell even if it's on a different sheet, or even on a different workbook) the timer stops!

I'd think that all this would require just a simple string/line inserted in my code. I'm really, really new to VBA and doesn't know how to write my own codes yet. I have to google what I need every time and do trial and error! Just to give you more info-- I'm using this for a call simulation program, in which the user is an operator taking in a call. She would have to be aware of how much time have passed after performing some actions/data entry on the different sheets on the workbook. I hope I've explained it enough. :D Anyway's here's the code I got, which I think needs just a few edits.
