Hello, we are building a form for a fishing club and we want our members to send us their fishing reports and i have some problems with some fields. I want 3 dropdowns (ecosystem, river, location). I have made a second list that contains the data of these 3 options, (i dont know if this is right). The second ccd (river) is depending on the first option (ecosystem) and it works but the 3rd (location) i cant make it work, i only see plese select so i need some help on how i must buld the lists and the elements. i just want the second dropdown depend on the first and the 3rd dropdown depend on the second option. i think it is simple but i am trying one week with no luck
