JS Variable with IF ELSE : <p>I am struggling here. My JS is below. 
The objective here - user selects type for course - WS or AC. 
If Onsite is checked update the AC value to be 1.5 under course weight.  </p>

<p>Number of people has differing values depending if AC or WS was selected. Hence in Calculate Total function there is an if statement reviewing the course type value - AC or WS. </p>

<p>JSHint is reporting on Line 257 - Expected a conditional expression and instead saw an assignment. </p>
