Conditionnal drop down list

[Helwings]

Hi,

I'm not an experienced developper, but I understand the logic of filemaker. I don't know if Filemaker can do this. I made some search and did'nt find any exemple about this criteria. I think that's a conditional Value list but not sure.

I have a drop down list with several item to choose.

If I choose one item, I would like to have a second drop down list of this item.

Ex:.

1st --------------- 2nd

drop down ------- Drop Down

===============================

car ---------> Ford; GMC; Chrysler

moto --------> BMW; Yamaha; Honda

boat --------> Bavaria; Tobago; Carter

First I made a Portal row with a dropdown list of my item. I tried to made a script but it does'nt work.
