Hi,

Thanks for all your suggestions. I was able to solve the issue with
the blank page. However, I'm still not passing any variables.

Basically the customer chooses a date in which to edit data. When he
does that, he is brought to another page where he can select the data
he wants to edit for that date. All those variables get passed
properly. Next, he selects the data to edit and is brought to an edit
screen. All that seems to work and the variables are passed. But,
when done editing and he returns to the previous page, no variables
are passed back.

The only difference is that when he saves the data, it calls a PHP
script to save the data, and then changes the header to return to the
previous page. Maybe I am not doing this correctly? I mean, from the
save script, it is just changing the location. It is not using a form
or anything.....

Thanks!

John.
