cfrgrid will not edit

When I attempt to edit my grid the following error is returned. error invoking CFC /design /Regstration.cfc : The PAGE argument passed to the getData function is not of type numeric.

My getData function: code:

<!--- Get data --->

        <cfargument name="page" type="numeric" required="yes">

        <cfargument name="pageSize" type="numeric" required="yes">
