Oh...and there won't be any error message.

It's perfectly legal to do

Code:

document.getElementById("imageCaption").innerHTML = make+model;

Just that neither make nor model will be defined.

(And they woudn't be even if you DID pass three values when you called the function. Do you see why? HINT: JavaScript is CASE SENSITIVE.)
