FormParameters not being passed

[jim_denney]

I am using a ModalPopupExenter to handle inserting new records into a GridView in VS2008. I am calling a stored procedure in SQl Server 2008 to handle the inserts and updates.

When I try to save the data from the modal popup, the procedure is called but no values show up in the data table. If I set default values on the FormParameters, they are inserted, so the values are not being read from the modal popup. Any ideas what I am doing wrong?

[CODE]
Code calling the procedure:
InsertCommandType="StoredProcedure" InsertCommand="AddUpdateTrainingCourse">

<InsertParameters>
<asp:formparameter Name="pKey" FormField="tbxpKey" DefaultValue="-1" />
<asp:formparameter Name="fkSponsor" FormField="tbxSite" />
<asp:formparameter Name="EndDate" FormField="tbxEnding" />
<asp:formparameter Name="Hours" FormField="tbxHours" />
<asp:formparameter Name="StartDate" FormField="tbxStarting" />
<asp:formparameter Name="Title" FormField="tbxCourse" DefaultValue="It is not passing anything..."/>
<asp:formparameter Name="Trainers" FormField="tbxTeachers" />
</InsertParameters>

Code for the popup:
<div>
<asp:ModalPopupExtender

Code from the CodeBehind procedure to save the data:
Protected Sub ImgBtnMpeSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs)
SqlCourses.Insert()
End Sub
