Hello,

I would like to create a python script tool with three parameters. Choice list for a parameter should be genereted automatically (like here: Generating a choice list from a field) but depending on the selection from the list. 

For example, if for first parameter we select from automatic list the value "12", the automatic list for second parameter should be filtered to value "100", "200" and then If we select "100", the list for third parameter should be filtered to "1000","2000", "3000" etc. 

Column 1 (parameter 1)
Column 2 (parameter 2)
Column 3 (parameter 3)
121001000
121002000
121003000
122004000
134001000
134002000
133001000

Do you have any idea how to modify the validation code from here: Generating a choice list from a field?

Thanks,

Robert
