About Drupal CMS
So the problem was the following: I'm running a Drupal 7 website with Webform 3.0 and wanted to be able
to calculate some field values based on other input fields. I.e. height and width are given and the area
is returned on the next page of the webform.
A fairly simple problem, with (in the end) a simple solution, but one I've not been able to find on the web and required a significant amount of real hard-core code debugging.
