Can anybody give me some help?

I am trying to set the heading towards a point that is relative to the current position. 

This isn't working:
setheading towards [xcor+30 ycor+20]
It says,
towards doesn't like [xcor+30 ycor+20] as input



I tried defining two values to use



make "x xcor+30

make "y ycor+20

towards [:x :y]

and even though it know what :x and :y are it gives the same sort of error as before.



It only seems to like a liter pair of numbers within the brackets.



Does anyone know how to get towards to take less literal coordinates?
