List in Combo Box, when new item is selected put todays date in the adjacent column

Hi,

I have a spread sheet for equipment that gets loaned out on a regular basis. Cells B4 - B25 have combo boxes in them, with the options to select "On Loan", "In Stock Room" etc in them. What I would like to do is create something so that as the combo box is changed, i.e. from "In Stock" to "On Loan", a date changes adjacent to each combo box.

For example, combo box in B10 has been changed from "In Stock" to "On Loan". The adjacent cell records the date automatically that the combo box was changed.

Can this be done?

Thank you for your help on this.
