Thanks so much Derek!! Here is the relevant code, it is quite a mess as I am still learning this whole Javascript thing. Please forgive me :)I did not attach the whole thing because it is over 2000 lines, but hopefully I got all the right pieces. The main issue I am trying to solve now is zooming to a single feature from a row click in a datagrid that is generated after features are manually selected. Hope this makes sense.I really appreciate your help with this!
