Help creating simple notification system

Hi, i'm trying to create a simple notification system, where my game pushed a message to an aray. Whenever the array has a message in it, it's supposed to display that message for 5 seconds, then delete that message. The array is used sorta like a queue system, so when two notifications are sent at once, it will display them one after another.

When I try to build this, the program doesnt work after the first notification, and the que count I created goes into minus figures. Is there any way I could fix this?

Hope you can help <img src="smileys/smiley1.gif" border="0" align="middle" />

When there are messages queued, the event is triggered constantly so after 5 seconds the whole array is cleared instead of just one message.

Here is one way to fix it: Notification example

Thank you so much for that, it works perfectly :)
