Why does my Quiz rule stop working after adding an extra user profile condition? I have a Drupal 7 site, that uses Rules and Quiz.
I have a rule that adds a role after the user takes a specific quiz, which
work fine. Here are the details of it:


Event

After updating existing content
Conditions

Content is of type

Parameter: Contenido: [node], Content types: Cuestionario

Data comparison

Parameter: Data to compare: [node:nid], Data value: 1985
Actions

Add user role

Parameter: Usuario: [site:current-user], Roles: nivel2


Now I want a similar rule but add the new role only if a specific profile field in the user's profile, has specific content. The field is a selection of certain terms of a certain taxonomy.

So, I've cloned the above (working) rule, and added to it a condition. So that this new rule looks like so:


Event

After updating existing content
Conditions

Data comparison

Parameter: Data to compare: [site:current-user:profile-profile:field-ubicacion, Data value: Provincia de Chaco

Content is of type

Parameter: Contenido: [node], Content types: Cuestionario

Data comparison

Parameter: Data to compare: [node:nid], Data value: 1985
Actions

Add user role

Parameter: Usuario: [site:current-user], Roles: nivel2


Now in this case, this new rule won't work. I.e the role is not added. 

Why could this be?
Make sure to add a Rules condition Entity has field (related to your additional field in your first Rules condition). And make sure to add that Entity has field condition BEFORE the condition in which you want to perform that "data to compare".

That's also what is mentioned in the Rules UI when you're adding a "data comparison" condition: somewhere it says "The data selector helps you drill down into the data available to Rules. To make entity fields appear in the data selector, you may have to use the condition 'entity has field' (or 'content is of type')".

For a video tutorial that illustrates the importance of this Entity has field condition, refer to Data types and data selection, especially what is shown between about 13:30 and 17:30 in it.
