Help - indesign script code - dialog window preventing complete action

Can someone help me with a script code? I already have the code ready and done. This code does the following: 1) It breaks the texts into lines,2)  breaks these lines into boxes, 3) applies a paragraph style to each of these boxes and 4) creates a small dash above each text box (separate).

I created a dialog window (palette) so that I can choose which paragraph style to apply and whether or not I want this dash to be inserted. However, the action only runs once, because it is as if the window closed and the code did not continue. How can I adjust this?
