I try to load 2 tables in my QV document. Both are Excel files. In the first table I load dates when a customer starts and ends a subscription with us. Example:
In the second table i load the birthdate of the customer: Example:
Now i want to load in one of the tables the age of the customer when he started his subscription. This is easier in the rest of the document so i don't need to calculate the age in every chart i will use it.
