I am using SPD 2007, Sharepoint 2007. I have a list that has a column of Yes/No choices. I need to calculate the number of times "Yes" is chosen. Is there a way that this can be done with calculated columns? And if so, what is the formula? Thank you.

  • This can definitely be done (The solution, depending on your answers to the following questions, might be a little, well, 'creative' though). Do you need the number of Yes values in the whole list, for a view, or just for the items displayed on a page? And how do you need to consume this value? Right on the page? As a column in a list? – Derek Gusoff Aug 1 '13 at 18:22
  • I need the numbers in the whole list. It will probably have to be stored to a column that won't be used for anything besides storage. Once there, those totals need to be updated to another list, but that is for later. – James Fenton Aug 1 '13 at 18:45
  • We still need a little more requirements clarification. Do you need real-time data that is constantly being updated, or is this a one-time push to that secondary list? And if I may what is the ultimate purpose of this number? Maybe we can find a simpler way to implement the business value you are trying to create. – Derek Gusoff Aug 2 '13 at 2:46
  • Unfortunately it is real time. Anytime the primary list gets updated with a yes or no value, the second list needs to be updated with the correct number of "yes" selections. The number is just used as a quick reference, it is what the customer wants – James Fenton Aug 2 '13 at 12:08

The easy way: If all they need to do is see at a glance the number of Yes answers, just create a view on the list that groups items by that column. You'll get the count totals out of the box. You can then drop a list view web part that consumes that view anywhere you want on the site.

The hard way: If you go down the path of trying to store this value in a list, you are talking about a list item event receiver, which involves Visual Studio and farm code.

  • For now it will have to be a view. I don't have access to the server for testing so this will have to be a temporary solution. Thank you for all of your help and responding back so quickly. – James Fenton Aug 2 '13 at 13:22

Unfortunate not with a Calculated column as they are calculated at the list item level plus they only get updated when the list item is being updated.

You could use a group list view and and aggregate count function. Alternatively look at something like the Data View Webpart.
