Here you have an example about how to assing the value of a input to another

<input type="text" name="cogs1" id="cogs1" value="<?=$_POST[cogs]?>" 
     onchange="cogs(this.value)"/>
<input type="text" name="cogs2" id="cogs2" value="cogs"/>

<script>
    function cogs(value) {
        document.getElementById("cogs2").value = value;
    }
</script>
