To make myself 100% clear i attached screenshot with explenation.

Assuming the value of the button is 'czynnik, który miał decydujący wpływ' (might just want to make it 4, but thats up to you) 

and that the question field name is 'questionfieldname'

Put the following under the confirm' tab in the button field on row 4 

if (event.value=="czynnik, który miał decydujący wpływ"){
    this.getField("questionfieldname").display = 0;
}else{
    this.getField("questionfieldname").display = 1;
}

Thank you, for your answer.

While i try to imput what you created for me nothing happened. So i am wondering if i did it right.

Went into button 4 

And then i paste the code and nothing happened:(

Wardenburg, I could not be more greateful then I am now. This is working, as I imagined.

But is there any chance to show additional window between line 4 and 5? I mean move 5 down while additional question form 4 is coming?

Moving fields dynamically is not something I've been able to manage

but if you're alright with empty spaces between questions then you can do it in the same way as with the example just with different fields & names

I am not happy about empty spaces, but nothing more left then accepting it, i guess.

Once again thank you for your help:)!!!

A form script can certainly move field dynamically. Each field object has a "rect" property. Change this and you change the size and position of the field. 

[Wardenburg]

Thats pretty neat,

is this how youd adjust the rect values? (other than just outrightly inputting the coordinates?)

var f = this.getField("fieldname")
f.rect = [f.rect[0]+1,f.rect[1]+1,f.rect[2]+1,f.rect[3]+1]

Any documentation for better understanding the coordinates would be welcome
