Forms Data Controls :: Change ASP Label ID Attribute?

I am new in ASP.NET and I am having a problem in generating the ID of each label that I generate in ListView's ItemTemplate control. I use it like this :

<asp:SqlDataSource ID="JobCat" runat="server"
ConnectionString="<%$ ConnectionStrings:KROVAN %>"
SelectCommand="SELECT * FROM [TblJobCat]"></asp:SqlDataSource>
<asp:ListView ID="ListView1" runat="server" DataSourceID="JobCat">
<ItemTemplate>
<li>
<a href="Jobs.aspx?CatID=<%# Eval("JobCatID") %>"><%# Eval("JobCategories") %></a>
<asp:Label ID="label<%# Eval("JobCatID") %>" runat="server"></asp:Label>
</li>
</ItemTemplate>
</asp:ListView>

When I run it, it says Parse Error. So is there any solution than can be done to change the label ID like this?
