Your call to dlg.show() actually returns the value of the button that was selected. You simply ignore it, that's all.

See Peter K.'s "ScriptUI for Dummies" ((ducks) really, that's the title!), the Guide to Life, the Universe, and Everything Else, as far as ScriptUI is concerned: http://www.kahrel.plus.com/indesign/scriptui.html

Please use the below source code, it will solve your problem:
