Syntax error... why ?

self unhide();

Unkown function, its : self show();

did that help?

The further error explenation should be shown in the console and the replacement of n by an actionslot, enables that the push to use key is shown correctly right away to every player.

For example: if u use self waittill ( "[{+actionslot 4}]" ); it will be the control customized by the player that is shown in a message and not the control you set up for it.
It just makes things easier.
