Gridview Edit is not working

I have a gridview and when I click the update button nothing is happening.  I do not get an error.  I'm sure it is something simple, but I am missing it.


<asp:GridView ID="gvLocations" runat="server" AllowPaging="True" 
    AllowSorting="True" AutoGenerateColumns="False" CellPadding="3" 
    DataSourceID="dsLocations" ForeColor="Black" GridLines="Vertical" 
        BackColor="White" BorderColor="#999999" BorderStyle="Solid" 
        BorderWidth="1px" AutoGenerateEditButton="True">
        <Columns>
            <asp:BoundField DataField="Location_Name" HeaderText="Location" 
                SortExpression="Location_Name" />
            <asp:BoundField DataField="Address1" HeaderText="Address1" 
                SortExpression="Address1" />
            <asp:BoundField DataField="Address2" HeaderText="Address2" 
                SortExpression="Address2" />
            <asp:BoundField DataField="City" HeaderText="City" SortExpression="City" />
            <asp:BoundField DataField="StateAbbr" HeaderText="State" 
                SortExpression="StateAbbr" />
            <asp:BoundField DataField="Zip" HeaderText="Zip" SortExpression="Zip" />
            <asp:BoundField DataField="column1" HeaderText="Co-Op"

                        DataSourceID="dsStoreType" DataTextField="StoreTypeName"

            </asp:TemplateField>
        </Columns>
    </asp:GridView>

    <asp:SqlDataSource ID="dsLocations" runat="server"

        SelectCommand="SELECT Locations.[Location Name] AS Location_Name, Locations.Address1, Locations.Address2, Locations.City, Locations.StateAbbr, Locations.Zip, Locations.[Co-Op] AS column1, Locations.StoreTypeID, StoreType.StoreTypeName FROM Locations LEFT OUTER JOIN StoreType ON Locations.StoreTypeID = StoreType.StoreTypeID" 
        
        UpdateCommand="UPDATE Locations SET Address1 = @Address1, Address2 = @Address2, City = @City, StateAbbr = @StateAbbr, Zip = @Zip, [Co-Op] = '[@Co-Op]', StoreTypeID = @StoreTypeId WHERE ([Location Name] = @LocationName)">

The very first thing I noticed is this:

'[@Co-Op]'

[Co-Op] = '[@Co-Op]'

Why????

Second, I don't see it declared in <Update Parameters>

I would try something like this:

[Co-Op] = @Co_Op

Then in update paramerts section I would have:

            <asp:Parameter Name="Co_Op" Type="String"/>
