Hi Guys

I'm slowly building a small calculation form.
I have an event switch in the output, where I do a small calculation in PHP.
Is it possible to save the result for use in a later 'box'? And how do I refer to the result later on?

Hi fribse,

Save the result to the $form->data[''] array and then use that value later.

Hi Bob

I'm sorry, i'm not that experienced in PHP, could you spell it to me, how I do that?
I know it's probably basic, but that's me :-)
I've created a hidden field, which I guess I have to, to have a place to store it, correct?

Ahh, you are absolutely right. Instead of using a complex set of 'event switch' and message boxes, and storing values, I could just use a custom code box, and put php in it with the switch in it, and all the calculations.
Much easier :-)
Now I just have to work on the multiplier thing, posted elsewhere, can't get my head around it...

Hi fribse,

That sounds good, To answer the question, you can pass data between boxes by saving it like this in one box

<?php
. . .
$form->data['some_name'] = 'some_value';
?>

and then use it again later

<?php
switch ( $form->data['some_name'] ) {
 . . .
?>
