FormIt - calculate/summate input-values

Hello there!

I'm using a multi-page FormIt-form, where the user can choose different checkboxes and radioboxes.

Depending on which check- oder radiobox the user did choose, the choosing get's rated by a value (between "1" to "5"). This happens in the "emailTpl"-chunk.
```
[[+age:is=`40`:then=`1`]]
[[+age:is=`50`:then=`2`]]
[[+age:is=`60`:then=`3`]]
[[+age:is=`70`:then=`4`]]
[[+age:is=`80`:then=`5`]]
<br />

[[+married=`yes`:then=`1`]]
[[+married=`no`:then=`0`]]
<br /><br />
```
What I want to achieve is that the different values get summated/calculated to receive a total-value.
- So I think I first need to set a new placeholder inside the "emailTpl"-chunk out of the existing placeholders/variables (like "age" and "married" in this example?
- Then I think I need a snippet which does the calculating? Is it possible to run a snippet inside the "emailTpl"-Chunk and send the total-value back, before the mail gets sent?
- Maybe it's better to work with a custom-hook before the email-hook?
Any help is highly appreciated....

So I'm trying to write a hook to do the calculation part...but I already fail to get the calculating-values related to the choice the user made...
```
<?php
$age= $hook->getValue('age');
$result = 0;

if ( $age == `40` ) { $result = 100; }
if ( $age == `50` ) { $result = 200; }

$hook->setValue('output', $result ); 

return true;
```
Then I use my new created placeholder [[+output]] in my email-template-chunk, but the output is wrong?! I expected at least that if I did choose "40 years" the output would be "100", if "50 years" the output would be "200", but it keeps the value "0"?
