IfElse nested not working

please check this code. which part is wrong

to catch-lizards
    let prey one-of lizards-here
    ifelse prey = "lizard2"
    [ show "WRONG" ask prey [die]
     set lifetime = lifetime + hawks-life-gain ]
    [ifelse droping-tail? = true
    [ask prey [set shape "lizard2"
    set lifetime lifetime + hawks-life-gain / 4 ] ]
    [ask prey [die]
    set lifetime lifetime + hawks-life-gain ]
   ]
  ]
end

problem is in place where (show "wrong") is written. that part doesn't execute. is syntax not correct?

In the ifelse prey = "lizard2" part, you compare whether the prey is the string lizard2. But the prey is not a string, it is an object having some properties, like shape or lifetime.

So you need to ask whether the shape of the prey is lizard2.

Update: Checking the shape of the prey probably looks like this:

ask prey [
  ifelse shape = "lizard2" [
    …
  ] [
    …
  ]
]
