1. Make the new ID for <label>
2. Loaded first the label element when script is executed.
3. Swap label and script elements and it will work!
4. Example:
...
<label id="label_TIP_Added_Comment" for="www.imagegambar.com"></label>
...
<script>
document.getElementById('label_TIP_Added_Comment').innerHTML = '*** Your new LABEL TIP! ***';
</script>
Or you can using another script command: .textContent .innerHTML .innerText or .value.
<script>
document.getElementById('label_TIP_Added_Comment').innerText = '*** Your new LABEL TIP! ***';
</script>
