Indeed, so with this choice of yours you are indisposed.

I shall explain again:

javascript:

....style.background-image

is incorrect because the '-' is the javascript substraction operator.

In javascript the '-' is to be converted to the capirtaisation of the next 
character:

....style.backgroundImage

>>Try:

Why wouldn't 1+1=2 be correct?
