Attached is an example of a data-entry form. Currently, a user form is activated when the button "Show Data-Entry Userform" is clicked. I will like that when a user select a data entry cell (all color coded yellow cells) a macro is run which open a user form with a drop-down-list to select the best entry. For example if cell "I7" is selected a macro is run which open a user form in order to select the best entry from a drop-down-list. Please, I need advice on which is the best way to run the macro when a data-entry cell is selected.
