Thanks a lot. Now it works perfect.Kind regards.

Hello,I need to create the next form... I want to select at the beginning of the form between 3 options (imagine: "Opt1", "Opt2", and "Opt3"). And after that, I want to make visible 10 different drop-down lists. I mean, if I choose "Opt1", the 10 drop-down lists related to "Opt1" will become visible...
