I’m getting a YSOD (Yellow Screen of Death) on this line of code: (Line 19)

Line 17:       <td valign="top">Geslacht:</td>
Line 18:       <td>
Line 19:         <% = Html.RadioButton("Gender", "M", Model.Gender == 'M') %> Man<br />
Line 20:         <% = Html.RadioButton("Gender", "F", Model.Gender == 'F') %> Vrouw<br />
Line 21:       </td>

Model is not null.

Anybody got any ideas?

UPDATE: It had to do with the fact that the field validation caused problems when multiple fields have the same name.
