Int wont work

Ok i have a sign im making and it holds xp levels. I did the math correctly and in eclipse it has no errors. Can someone help me this is for 1.2.3

PHP:

else if((player.hasPermission("xps.sign.interact.xpsbank") || player.hasPermission("xps.*") || player.hasPermission("*") || player.isOp()) && signline1.contains("[XPSBank]") && event.getAction().equals(Action.LEFT_CLICK_BLOCK) && (block.getType() == Material.SIGN_POST || block.getType() == Material.WALL_SIGN)) {
   if(player.getLevel() >= 1) {
   final int si = Integer.parseInt(signline4);
   final int siu = si + 1;
   final String siui = Integer.toString(siu);
   if(!signline4.equals(signline3)) {
   player.setLevel(player.getLevel() - 1);
   sign.setLine(3, siui);
   sign.update(true);
   }else{
   player.sendMessage(prefix2 + " You have reached the limit of " + signline3 + " levels!");
   }
   }else{
   player.sendMessage(prefix2 + " You don't have enough XP!");
   }
   }

 

Would you be so kind, and tell us what exactly doesn't work?

 

new code and when you left click the sign it makes an error message and stops the code.

Apparently there is a problem on line 250. What line is 250?

 

final int si = Integer.parseInt(signline4);

 

I can't really tell what the problem is, but are you sure what is on line 4 is an integer?

 

that should tell you everything - your source seems not to be convertible

 

its the number 0

I figured it out it was because in another class i was setting 0 as the color green thanks anyway
