End User cannot see 'My Requests'

Hi,

I have a problem with my Self Service Portal - on the self service portal I have a link for 'My Calls'  which brings up a dashboard with 4 Gadgets, 2 of which are Queries to display calls logged by the user with these filters:

Raise Useris current user

andStatus Is Completionequals False

andStatus Is Endequals False

This works fine for an Anaylst on both Incident and Requests but for End Users they can only see Incdent calls populated.  I was hoping you could direct me to the right place to look for the permission issue.
