I've a content type 'Content' with the field 'Value' (an integer). Every time a Content has been published, I'd like to grant the Content's author some User Points, equal to the value in the 'Value' field.

I tried solving the first part of my problem with the Rules module like this:

*Event: A node has been published

*Conditions: Content is of type 'Content'

*Actions: Grant points to a user: ...

However, it's impossible to pick node:field-value in the Points section. I also tried:

*Event: A node has been published

*Conditions: Content is of type 'Content'

*Actions:
   
 - Calculate a value: `[node:field-value]` "+" 0. (Variable name = result)

 - Grant points to a user: ...

But then, the variable 'result' is not available. How can I solve this issue?
