Syntax Error Check appropriate syntax for deftemplate in Clips ide

So I'm trying to build a program that takes user's input by displaying a message on the screen “Enter your subject”.

In the second rule, I'm to mention subject names “artificial intelligence”, “operating system” and “compiler construction” and check that entered subject from the first rule matches with the mentioned subjects by displaying this message on the screen. “Your entered subject is true”.

Here is the code:

(deftemplate subject
  (slot subject) 
  (slot artificial intelligence)
  (slot operating system)
  (slot compiler construction)) 

(defrule reading-input
  (printout t "Enter your subject:")
  (assert(var(read))))
  (defrule checking-input
  (var? artificial intelligence)
  (var? operating system)
  (var? compiler construction)
  (com(artificial intelligence ? artificial intelligence))
  (test(=?artificial intelligence ? artificial intelligence))
  (test(=?operating system ? operating system))
  (test(=? compiler construction ? compiler construction)) 
  (=>
  printout t "Your entered subject is true:"))
