thread replies: set default Title field text?

[gabeanderson]

According to my newreply template, the title field should be
auto-populating with the thread title, but it's not. Here's the code
from newreply:

<td><input type="text" class="bginput"
name="title" value="RE: $title" size="50" maxlength="85" tabindex="1"
title="$vbphrase[optional]" /></td>

The value="$title" suggests that the title text should pull in the
thread title value, but it's not displaying when I reply to an existing
thread. I've posted a screenshot highlighting the problem here:

Note that the only Title field value that displays is the reply template is "RE:," even though the code tells the value to be "RE: $title." In this example, I want the title field value to default to the following:

"RE: Errors opening up an emailed presentation"

Thanks,
Gabe

Any suggestions? This doesn't seem to me like it should be very difficult. Thanks!

This was all it took:
