Responsive GUI

I’m trying do responsive GUI so I create props:
[java] prop = new Properties();
prop.setProperty(“buttonAX”, game.getContinueButtonx());
prop.setProperty(“buttonAY”, game.getContinueButtony());
prop.setProperty(“buttonBY”, game.getNewGameButtony());
prop.setProperty(“buttonCY”, game.getOptionsButtony());
prop.setProperty(“buttonDY”, game.getAboutButtony());
prop.setProperty(“buttonEY”, game.getQuitButtony());
nifty.setGlobalProperties(prop);[/java]
(those game.get give me int converted to string values)

and in my GUI.xml:
[java] <control x="${PROP.buttonAX}" y="${PROP.buttonAY}" width=“200” height=“50” label=“Continue” align=“center” valign=“center” visibleToMouse=“true”>
<interact onClick=“continueGame()”/>
</control> [/java]

but button is invisible? What’s wrong?

EDIT:
FIXED
forget about name field
