I am about to do <dtml-call "REQUEST.set('a', (a - b) * 15">

I presume that should be: <dtml-call "REQUEST.set('a', (a - b) * 15)"> ? ;-)

Anyway, two options:

1. On your form, change your input to be: <input type="TEXT" name="a:int">

2. Change your call to be: <dtml-call "REQUEST.set('a', (_.int(a) - _.int(b)) * 15)">

cheers,

At the same level, what is the easiest way to calculate the difference (in minutes) between two given times in a form (HHMM)? Is there any easy way to do this or do I have to do something complicate?
