Create a dynamic filter with variable ranges

[Pedro_Rodriguez]

Hi all,

I'm requested to do a dynamic, custom-ranged filter. In the attached file there's a sample of data: code and amount.

My requirement is, there have to be three intervals in the filter, but the interval limits between the first & second and second &third interval have to be customized.

So I want to end up with something like this, a list box with the 3 intervals plus a, imput box with 2 variables where the user can introduce the 2 middle ranges (instead of the 60 and 120):

        

I tried somthing with the class function but ended up with something different.

Thanks a lot in advance
