syntax error in c# using repeaters

Hi,
I have a repeater in my asp.net code which gets all the events in a particular month and then using the dates found in the database I have a nested repeater to search for all events in that date, then a further nested repeater searches to see if the events found have a value in a particular field.
I think its nearly working but i'm stuck with the syntax on the second repeater.

 foreach (RepeaterItem repeaterID in Repeaterday.Items)

i have an error that Repeaterday does not exist in the current context

I'm not sure what to change it to, i tried Dataset.Items which it doesnt like either

Please help!
Thanks
