Problems retrieving data from form fields for non-encrypted host

I'm pleased to say that I have a small web service client that runs in
Mozilla's javascript. I can add two numbers as long as I hard code the
addends in the java script.

However, when I try to retreive the addends from some form fields, I get a
dialog box that says I'm sending data to an unencrypted host and there is a
single OK button.

Unfortunately, I clicked the checkbox that says "do not show this message
again". I wish I had not done that. How do I undo that?

Anyway, prior to having unchecked that check box, I could see that they (the
web service and client) were performing the addition correctly but as soon
as I clicked the OK button, the form was restored to its previous state.

How do I tell netscape it is OK to send my data unencrypted to my web
service?

Thanks,
Siegfried
