I have a php page, which launches a popup window containing a form with checkboxes. The originating window includes an external stylesheet.

The form html for the popup window is:

```
<form name="statusForm" action="post.php=" method="post" enctype="multipart/form-data">
<label for="Test">Test:</label>
<input name="checkboxes[]" value="Test" type="checkbox">
<br>
<label for="Test">TestTest:</label>
<input name="checkboxes[]" value="Test" type="checkbox">
<br>
<label for="Test">TestTestTest:</label>
<input name="checkboxes[]" value="Test" type="checkbox">
<br>
<input name="Submit" value="submit" type="submit">
</form>

```

The form has been trimmed, and fields renamed to test for posting..

In the external stylesheet, I have:

```
label {
    min-width: 5em;
}

```

The checkboxes are still not aligned. Do I have to included the stylesheet explicitly in the html of the popup window, or is it something else?
