Hi howardR,

Thanks for your post. I myself are about the half of your road
Actually struggling to dive deeper into programming with Zorro. Still a lot to learn.
I downloaded Zorro the first time back in 2016, but never used it for a loooong period of time.
Since a little more than a year i am forcing myself now to learn Zorro. Wish i would have done learning immediately after first download.
Wasted a lot of time with the same things like you did.
May i ask what kind of filter you are looking for?
