Zoom and "Ask a Question" Feature not working "Streamline" Theme

I have a problem with the zoom feature on product images. It will not pop up the image and allow user to zoom in on product photos.

Also on a few of my product pages the “Ask a Question” drop down menu is not working.

Any tips on how to fix these problems?
