I have one stored procedure returning data based on parameters.
I execute the stored proc for report1 with a date of 20050712 and receive data. I then populate a datagrid with this dataset.

But when I execute the stored proc with the same date, but different report(report2). I get the error.

WhenI execute the proc for both reports on the backend they both give me data.

Any ideas?

Here is my code:

Private Sub cmdSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdSubmit.Click
        Dim sDate As String
        Dim sReport As String
        Dim sEmpNameId As String
        Dim sAgentId As String
        Dim sErrorText As String
        Dim bCreateReport As Boolean
        sDate = txtDate.Text
        sReport = ddlReport.SelectedValue
        sEmpNameId = ddlEmployee.SelectedValue
        sAgentId = ddlAgentid.SelectedValue
        sProject = ddlProject.SelectedItem.Text

        lblResult.Text = ""

        If Len(Trim(sDate)) = 0 Then
            sErrorText = "You must enter a Calldate"
            lblResult.Text = sErrorText
        End If
        If Trim(sReport) = 0 Then
            sErrorText = "You must select a Report"
            lblResult.Text = sErrorText
        End If

       If Trim(sEmpNameId) <> 0 And Trim(sAgentId) <> 0 Then
            If Trim(sEmpNameId) <> Trim(sAgentId) Then
                sErrorText = "AgentId and Employee Name Must Match"
                lblResult.Text = sErrorText
            End If
        End If

        If Len(Trim(lblResult.Text)) = 0 Then
            bCreateReport = CreateReport(sDate, sReport, sEmpNameId, sAgentId, sProject, sErrorText)

            If Trim(sErrorText) <> "Success" Then
                lblResult.Text = sErrorText
            End If
