Additional resources in the OGL 5E character sheet are accessed using identifiers like these: repeating_resource_$0_resource_left repeating_resource_$0_resource_right repeating_resource_$1_resource_left repeating_resource_$1_resource_right How can I determine if there are any, and in that case how many of these are present? I can access the field directly using: getAttrByName(charId, 'repeating_resource_$0_resource_left'); However, this logs an ERROR to the console if there are none.
