what i want to change the name fields in this html by the variable i

I believe this is what you are trying to accomplish.

I changed regular single quotes into a template literal

 var i =1; function add_fields() { var emptydiv = document.createElement('div') emptydiv.innerHTML = `<div class="col-12 col-md-6"><div class="group"><input type="text" name="${i}" required><span class="highlight"></span><span class="bar"></span><label>Attributes</label></div></div><div class="col-12 col-md-6"><div class="group"><input type="text" name="Size" id="Size" required><span class="highlight"></span><span class="bar"></span><label>value</label></div></div></div>` document.getElementById('addable').appendChild(emptydiv); i++; console.log(i) return emptydiv; // console.log("Hello world") } add_fields();
 <div id="addable"></div>
