Forms Data Controls :: How To Make A Cell On A GridView To Be Link On A Page

im just trying to use this answer, but im getting an error on my page:

"A field or property with the name 'returnantID' was not found on the selected data source."

Im not really sure what the "returnantID" is but it appears my page isn't liking it, not sure if i was sopposed to cswap it out for some other data or not.

This is my current gridview:

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" GridLines="None"
DataSourceID="ObjectDataSource1">
<Columns>
<asp:BoundField DataField="ProductName" HeaderText="ProductName"
SortExpression="ProductName" />
<asp:BoundField DataField="Price" DataFormatString="{0:c2}" HeaderText="Price"
SortExpression="Price" />
<asp:BoundField DataField="Length" HeaderText="Length"
SortExpression="Length" />
<asp:BoundField DataField="Engine" HeaderText="Engine"
SortExpression="Engine" />
<asp:BoundField DataField="Colour" HeaderText="Colour"
SortExpression="Colour" />
<asp:BoundField DataField="Description" HeaderText="Description"
SortExpression="Description" />
</Columns>
</asp:GridView>

would just like the ProductName to link to the corresponding products page(using its Id)

p.s this is what i tried:

<asp:HyperLinkField DataNavigateUrlFields="returnantID" DataNavigateUrlFormatString="Details.aspx?id={0}" DataTextField="ProductName" NavigateUrl="Details.aspx" />

**Update** I changed the "returnantID" to "ProductName" which turned the name of my product into a link but clicking that link gave me this new error:

Input string was not in a correct format.
