IF > THEN show(?) form

Hey,

I have an element formula to show certain options when an item from the dropdown is selected. Each dropdown element should have diffrent checkbox options.

What I want to archive is:

When selected “Citybug” from the dropdown menu show >
checkbox option “backwindow”, value = € 85
checkbox option “sidewindows”, value = € 80
checkbox option “frontwindow” value = € 260

When selected “Hatchback” from the dropdown menu show >
checkbox option “backwindow 2”, value = € 95
checkbox option “sidewindows 2”, value = € 105
checkbox option “frontwindow 2”, value = € 260
checkbox option “backdoor windows”, value = € 90

*prices are fiction.

I found this topic with a possible sollution:

(type_of_proofreading*formatting*wordcount*(IF(AND(wordcount<5000,completion_times=0.992),0.9,IF(AND(wordcount<5000,completion_times=0.993),0.95,IF(AND(wordcount<5000,completion_times=1),1,IF(AND(wordcount<5000,completion_times=1.5),1.5,IF(AND(wordcount<5000,completion_times=2),2,.......IF(AND(wordcount>25001,completion_times=2),0,"")))))))))))))))))))))*discounts)

My problem is that I can’t make much sense out of that code, since it contains a lot of id’s that aren’t clear to me.

Can anyone clearify this for me or help me fix my current form.

Regards,
Roelof.

PS: The person in this topic seems to have the same problem as me. (sort of)
