netlogo - LINK expected input to be a number but got the turtle (turtle 26) instead -

-

how can assign link variable. there run time error in code when run line

let link-who link node2-who this-one

node2-who , this-one turtles.

and runtime error :

link expected input number got turtle (turtle 26) instead.

the procedure link takes who numbers of 2 turtles , returns link connecting them. you're getting error because @ least 1 of inputs you're giving turtle, not who number.

now, said, recommend avoiding using who numbers @ (except in special circumstances). instead, if want link between current turtle , other turtle, can do

link-with other-turtle

where other-turtle other turtle (it called node2 in case).
