Help with elseif strurl to control value of a form

[doug123]

Hi,

I've looked around the web for a way to control a strurl value in a form.
Example: I want to send info in a strurl such as:

http:example.com/form.shtml?field1=1&field2=2

Then on the form, "<field1 value=1>", and "<field2 value=2>",
and if there is no strurl info sent such as http://example.com/form.shtml

field1 value="", field2 value=""

Regards,

Douglas
