How to add a date picker / Calendar from clicking a cell

Hi Guys. I am trying to add a date picker - so when you click on a cell, it opens up a mini calendar that you can select a date on, which will then fill that cell with the selected date.
I know that there is supposed to be a Calendar form control, but My version doesn't seem to have it, and when I go to add additional controls, it isn't there either. Is it possible to do this with my version?
(I am using 2007)
Thanks in advance.

Thanks for this.
Okay, so now I have this control installed.... but using it??... crikey.. I keep getting a run time error - object required message no matter which cell I click.

I have never used macros or active x controls before, so this part makes no sense to me....
Looking at http://blogs.office.com/b/microsoft-...e-pickers.aspx this is exactly what I need, but nothing tells me how to use it on my own sheets...?

Are you able to walk me through it step by step from the start at all?... sorry to be a pain, but once the penny drops and I understand how it works, I'll be fine...Activity sheet test.xlsm

I've added my currently basic sheet, and entered notes in the cell

Thanks

okay... thanks anyway...

I did a change to the code, seems to work fine.
