Nested Query Repeater

I was using that as the basis for adding a nested query repeater to my news pages that would display a list of media contacts based on geographical region and associated/relevant business units.

This code:

 <cms:queryrepeater StopProcessing="false" runat="server" ID="qrContacts" QueryName="custom.news.NewsMedia" TransformationName="custom.news.NewsContact" OrderBy="LastName ASC" /> 

<script runat="server">

    protected override void OnInit(EventArgs e)
    {
        base.OnInit(e);
        if (this.Parent is IDataItemContainer)
        {
          IDataItemContainer cont = this.Parent as IDataItemContainer;
          if (cont != null)
          {
            qrContacts.WhereCondition= "nodeAliasPath = '" + Eval("NodeAliasPath") + "'";
            qrContacts.ReloadData(true);
          }else
          {
            Response.Write("Error: IDataItemContainer is null");
          }
        }
    }

</script>

Was added to the transformation that displays the news detail. The code in the custom.news.NewsContact transformation is basic display:

<%# Eval('FirstName') %> <%# Eval('LastName') %><br />
 <%# Eval('Company') %><br />
 <%# Eval('Phone') %><br />
 <a href="mailto:<%# Eval('Email') %>"><%# Eval('Email') %></a><br />

If I replace that code with text for testing purposes, it displays correctly, however whenever I have that code in place I get:

error CS1012: Too many characters in character literal

I have checked the query, it returns the correct data, and has been used on a normal, no nested repeater. The error is vague but it seems as if there is a disconnect when trying to load the data dynamically? Is there a setting I am missing? Anyone else ever experience this?

Thank you in advance.
