(the pictures will be available this evening)

I need texboxes during a setup project (like TextBoxes (A)- see
pictures prob1 and prob2): here I enter values to be passed, these
value I pass and a form captures it (prob3.jpg).

My problem is that the arguments that are passed, are the standard
values (and not the one that are filled in), so the custom action is
fired to early ...............................

Does anybody knows a solution?

It is necessary that the Textboxes (A) schould be at the end, because I
need to change values of a file that is installed.........

Hope somebody can help me out.....
