Do you know how to auto populate the "Date" in a Numbers spreadsheet?

I've looked everywhere for the solution and couldn't find a thing. Here is what I have. Column "A" of my spreadsheet is the "Date" column. The rest of the columns are text or data. What I want to happen is column "A" will autopopulate "Todays Date" when any data is entered in column "B". If you can figure it out you are definatly smarter than the average bear.

Any suggestions or comments would be appreciated.


Thanks for looking
