Hi Everyone,

I've joined this forum in the hopes that someone will be kind enough to create something for me as my knowledge of excel does not exceed much further than formulas.
Essentially I need a list of countdowns for my store. The sheet will be for the tester, who gives testing times to people who wish to sell their gadgets and games consoles etc. What I need is a spreadsheet that has the following columns:

A: Name of item
B: Testing time (hh:mm:ss)
C: A countdown, preferably turning red when the count drops below 5 mins
D: A button to start the count once the item is given to the tester

The list needs to be about 30 rows in length. I have managed to find formulas to create a single countdown but I cannot figure out the button part and cannot work out how to have multiple countdowns.

Obviously columns C and D are what I am looking for help with.

Any help or advice would be much appreciated, bearing in mind that I know little to nothing about macros etc.

Thanks

Dave
