Having difficulty with Microsoft date & time picker in excel 2010
 

I am able to chose MS date & time picker 6.0 (SP6) from the drop down for active x control add ins, but when I choose it and attempt to insert it into a cell, an error window pops up and says "cannot insert object". anyone have any suggestions how to fix this. I am trying to create a drop down calendar for date selection on an excel spreadsheet.
