Cascading comboboxes problem (1 Viewer)

[xytras]

Hi!
I want to use cascading comboboxes but when i'm setting criteria for second combo box, the "combo box form value" is not visible. i've tried to use the same names as in example form. It didn't work.
I have always the window asking for value of the parameter.
What should i change ?

Thank's for any help
