I found one link to a pdf file, and you had the link written incorrectly. Go
back and write them like this one:
http://www.awanacentralcal.org/OtherFiles/EventParticipationAgreement.pdf

As per opening in a new window...why? I can see it if you are opening an
offsite link, but this is to your own website, and the viewer only has to
click the back button??? It will complicate life for the viewer to open the
second window...

But if you must, then this is one way. Insert this code snippet via the
insert html code fragment tool somewhere it won't be in the way on your
page:

<script language="JavaScript" type="text/javascript">function Show(Url,
Name, Features) { window.open(Url, Name, Features); }</script>

and then change the hyperlinks to:

javascript:Show('http://www.awanacentralcal.org/OtherFiles/EventParticipationAgreement.pdf','newwindow','')

You will probably need to write your links, copy, and then use Ctrl V to
paste the links into the address field in the hyperlink dialog, otherwise
you are likely to make mistakes.
