id types are pointers by default so you don't need to include an * in the name (just fyi). here is how you declare an id variable:

id variableName = someValue;

in this case it needs to have a nil value and be named thing

being nil a value of 0, right?

no nil meaning nil. like

int a = nil;

got it thank you..
