I am working on Drupal 7 on a custom content type that is called Event.
Each created Event is programmed to be displayed for 1 hour before been deleted. I am using rules component scheduler for that and it works well.
Now I need to be able to increase that display duration.
I already created a numeric field called duration that take the value of the duration from the user. That value that I want to add to the initial display duration.
I need to use that duration field in the Scheduled evaluation date. But rules denied using the + with an identifier.
Can anybody help ?
How do I increase the duration of a tasks that has already been scheduled on node creation. How do I do that using a field that take the value to add?
