Hi,
ok you can put the list on a sheet you don’t use i.e. last sheet in the workbook( copy the list above), once you have pasted the list on the last page go to the cell you want the data to be (once you have chosen it leave it selected) now go to Data, then Validation, then choose List from the Allow drop down. Next click the source and high light your list that you put on the last page, click ok.
If you go to the cell you get a drop down arrow click it and a list appears chose a time and that’s it .
There are a few other methods using combo or list boxes but these are a little more involved using Index function
hope that helps
