When I put in a boolean it asks for an Actor but when I try and Actor it asks for boolean

This is the code

if(leftWallCheck = null)

and comes up with the error: found greenfoot.Actor expected boolean but if I try

if(leftWallCheck = false)

and comes up with the error: found boolean expected greenfoot.Actor

What is 'leftWallCheck'? Is it a boolean? If yes, change the '=' to '==' and use true or false. For your info:

if (leftWallCheck)
//is the same as
if (leftWallCheck == true)

//and
if (!leftWallCheck)
//is the same as
if (leftWallCheck == false)
