get value back from calculation

[GBailey11]

I'm sure that's an easy one but it sure wrecked my head today! :-)

Anyway, I've got a HTML form with some values (integers) that I want to be added together. For this to work, I've referenced an external php file in 'action=calculation.php' of my form.
Now my problem is that if the calculation runs in that php file, how do I get the value back into my HTML form so the added numbers will show up in it? (The calculation and the echoing of the total value works fine if I keep everything in the HTML file but I'd just love to separate the structure from the code).

Thanks a lot for any help with this in advance.

I guess there is a number of ways you could do this. One suggestions would be, if the calculation is successful, on the calculation.php page you could include the original page and then the variables would be available for it.

you could use headers() to redirect the user back to the other page, but make sure you pass the result by $_GET vars or via sessions.

Does that help?
