Scrolling On Secondary Images (Product Page)

[JuanCastells]

Hi,

 

Could any of you please advise on how I can make the left scroll to appear on the secondary images on my product page?

I think the issue is the highlighted part below but  I don't know where to fix it.

 

Many thanks in advance.
