What's wrong with this asp.net markup?

Question

<%# Convert.ToDateTime(Eval("Posted")).ToShortDateString() %>

It tells me Invalid Expression term ')' . The code still runs fine though, it's just annoying.

This is the full markup:

<p>
Last Updated:
<%# Convert.ToDateTime(Eval("Posted")).ToShortDateString() %>
</p>

Answer 1

Tried deleting it and retyping it out (not copy and paste)?

This sometimes works for me when I get obviously incorrect errors in the editor.
