I am doing this in front end, i have these 2 fields: Lunedì_open, Orario_Fine_Part and i have to check if Orario_Fine_Part is less than an hour from Lunedì_open. in other words i have to check if Orario_Fine_Part is between Lunedì_open and Lunedì_open+1 h. thanks
Okay, so what exactly do you want to see when the condition is NOT met or when it is met? Anther column where it says... Yay!! Condition Met. Nay!! it failed? Or something along those lines or you want to exclude those rows for your chart where the condition have not met? What exactly are you looking to do?
