Error 1 ; expected 

    <%if (Model.ReferenceFields != null)
          {%>
            <%int count = 1; %>

            <%foreach (var referenceName in Model.ReferenceFields)
            {%>
             <%var value = "value"; %>
             <%count++; %>
             <%value = value + count.ToString(); %>
            <tr>
                <td><input type="hidden" name="Tests.Index" value='<%value%>' /></td>

The basic problem is lines like this

<input type="hidden" name="Tests.Index" value='<%value%>' />

So you're wanting to write out the contents of value into the html but thats not the way to do it. It should be

<input type="hidden" name="Tests.Index" value='<% Response.Write(value); %>' />

or a shortcut for Response.Write is <%= so

<input type="hidden" name="Tests.Index" value='<%= value %>' />

The other problem is that the formatting of your code is, quite frankly butt ugly and you're making it hard work for yourself when trying to read it. Try this instead.

<%
if (Model.ReferenceFields != null)
{
    int count = 1; 
    foreach (var referenceName in Model.ReferenceFields)
    {
        var value = "value";
        count++;
        value = value + count.ToString(); 
        %>
        <tr>
        <td><input type="hidden" name="Tests.Index" value='<%= value %>' /></td>
        <td><input type="text" name="Tests['<%= value %>'].Value"/></td>
        <td><input type="button" value= "Add" /></td></tr>
        <%
    }
}
%>
