Hi! Niraj
Thank you for your response, i used your formula but isn't solve my problem.
The thing is that i have two input controls, in one i have 6 months and the other i have 7 months.
The first one works because when i choose "All Values" it displays "June Acumulado 2015" but when i choose the second input control it displays the same text! and it's wrong because i need to display "july acumulado 2015".
I attached a picture just in case it would help.
