服务器标签格式不正确-ID中的Eval错误

Question

I am having an issue with my Asp.NET app, in the HTML section, basically the issue comes from the EVAL value which is the "Id" properly, so I've tried using an RadioButton and Input, but any of them work properly.

This is my Asp.NET code.

<div class="row justify-content-center">
    <div class="col-lg-3">
        <div class="item">
            <input runat="server" id="AnswerID<%# Eval("Id") %>_Nunca" type="radio" name="GrupID<%# Eval("Id") %>" value="Company" class="required">
            <label for="AnswerID<%# Eval("Id") %>_Nunca">
                <img src="Content/img/seo_icon_1.svg" alt="">
                <strong>Nunca</strong>No, Nunca
            </label>
        </div>
    </div>

    <div class="col-lg-3">
        <div class="item">
            <input runat="server" id="AnswerID<%# Eval("Id") %>_Aveces" name="GrupID<%# Eval("Id") %>" type="radio" value="Private User" class="required">
            <label for="AnswerID<%# Eval("Id") %>_Aveces">
                <img src="Content/img/seo_icon_2.svg" alt="">
                <strong>A veces</strong>Si, Algunas veces
            </label>
        </div>
     </div>

    <div class="col-lg-3">
        <div class="item">
            <input runat="server" id="AnswerID<%# Eval("Id") %>_Siempre" name="GrupID<%# Eval("Id") %>" type="radio" value="Private User" class="required">
            <label for="AnswerID<%# Eval("Id") %>_Siempre">
                <img src="Content/img/seo_icon_3.svg" alt=""> 
                <strong>Siempre</strong>Si, Siempre
            </label>
        </div> 
    </div>
</div>

This is the error:

Server Tag is not well formed.

I am not sure what's the issue, I have seen several similar questions, but no gives a real answer.

Thanks in advance.

I haven't done this in ages, but it looks like you have the double quotes nested. Try changing some of them to single quotes.

Try

 <div class="item">
                <input runat="server" id="Radio1" type="radio" name='GrupID<%# Eval("Id") %>' value="Company" class="required"/>
                <label for="AnswerID<%# Eval("Id") %>_Nunca">
                    <img src="Content/img/seo_icon_1.svg" alt=""><strong>Nunca</strong>No, Nunca</label>
            </div>
