                &lt;td&gt;@Html.TextBox("codeTextBox", discount.Code) &lt;/td&gt;
                &lt;td&gt;&lt;input type="checkbox" name="freeShippingCheckBox" id="freeShippingCheckBox" checked="@discount.FreeShipping" /&gt; &lt;/td&gt;
                @if (discount.isTwoForThree == true)
                {
                    &lt;td&gt;&lt;input type="tel" value="Ta 3 betala för 2" readonly /&gt;&lt;/td&gt;
