Question: IS there a way to add/subtract time from a start time and add/subtract time from an end time in one cell.

This is a time sheet. My boss would like to account for travel for our workers. IF you show up at 10:00 pm. he would want me to enter 10:00 pm, but the excel to show 9:30 pm. And if you left at 11:00 pm, he would want me to enter 11:00 pm, but it show 11:30 pm.

I believe this is a macro, but I am not very educated when it comes to macros.

Answer: 
A classic JavaScript line should just do the job:

document.getElementById('processorTitle').innerHTML=' new text ';
Form elements have text properties, but other HTML elements (like the `H4` in your example) do not. Instead, they have `innerHTML`.

In plain JavaScript, you can access the innerHTML:

```
document.getElementById('processorTitle').innerHTML;

```

or change it:

```
document.getElementById('processorTitle').innerHTML = 'your text';

```

To use jQuery to access the value of innerHTML, use `.html()`:

```
$('#processorTitle').html();

```

or change it:

```
$('#processorTitle').html('your text');

```

If you continue to have trouble after making this change, be sure that you included the jQuery library into your page to use the jQuery features:

```
<script src="https://code.jquery.com/jquery-2.1.3.min.js"></script>

```
