As the Web master at the Herp Trader I can say with assurity that there is nothing special about the pages in question. It is after clicking the submit button that things start to get clever.
For those that have knowledge of the internals of web pages it is just your basic HTML form. I don't even think there is any Java Script validation of the data. All that is done in Perl after clicking the submit button.
When you experience this problem it might be worth checking other pages with forms on them. (Eg:
www.whitepages.com.au or any of your regular haunts where you enter data into boxes.)
Clearing out your temporary internet files may be of assistance to you in resolving the issue if your browser has got itself in a knot. (Not just at the Herp Trader but anytime you experience this sort of problem.)
To do this in Internet Explorer follow these steps
*) Open Internet Explorer
*) Click on the Tools button
*) Select Internet Options
*) Under the heading Temporary Internet Files under the General tab, click the button Delete Files
*) Another dialog box will open, tick the option to, Delete all offline content
*) Click Ok
*) Once complete visit the Herp Shop Website,
www.herpshop.com.au .
*) Hold down the Control (Ctrl) button and then press the F5 button, this will reload the Herp Shop / Herp Trader website.
*) Once complete attempt to access the pages you were looking for
Someone changed my signature and I am not happy 
I use internet Explorer! Gosh I feel so obsolete, does this mean my beta video is out of date too? LOL
