Solution :

By definition, your for attribute value must match your id attribute value of “another” form control, to use your HTML 4.01 terminology. The  Controls are created by the input, textarea, button, select, or any object elements, so you need to just read “another” as “a”. HTML5 understands it very differently, specifying that your attribute must refer to the labelable element.

From your error message, it is clear that you are trying to validate against HTML5, so your rule that will apply  is that your for attribute must be referring to the button, input other than the with type=hidden keygen,/meter/output/progress/select, or the textarea element. My suggession is that you must have forgotten the id attribute and you are incorrectly assuming that your name attribute could do the job for you.

I hope my suggestions will help you in resolving your issue.

Solution:

What This Implies

This error is saying you that a <label> within a <form> uses a for attribute inaccurately.

The for attribute of a <label> is employed to associate a label with appointed form input. It should comprise the id of the input to which it is associated. Leaving the for attibute blank or referring to an input that does not subsist is not approved.

The label for attribute should comprise the input id value

<label for="foo">Foo:</label>
<input id="foo">

To throw away the for and id attributes all-together, place input inside label

<label>
    Foo: <input name="foo">
</label>

Further note, that input cannot be hidden <input type="hidden">, but it can be styled as hidden <input style="display:none">

In case you employ the for attribute in a label element it has to match the id of an input element in your form.

<label for="field-id" style="line-height:24px;">Your Name</label><br>&nbsp;&nbsp;
<input type="text" id="field-id">

By definition, the for attribute value should match the id attribute value of “another” form control, to employ the HTML 4.01 terminology. Controls are made by inputtextareabuttonselect, or object elements, hence only read “another” as “a”. HTML5 puts this somewhat diversely, secluding that the attribute should refer to a labelable element.

From the error message, it appears that you are validating against HTML5, hence the rule that executes is that the for attribute should refer to a buttoninput (other than with type=hidden), keygenmeteroutputprogressselect, or textarea element. My guess is that you only forgot the id attribute, inaccurately pretending that the name attribute could do its job.
