Hi,
Your website is having jQuery conflict issue and this should be resolved. Then everything will be good to go.
The conflict is caused because of loading multiple jQuery in a single page.
The 1st jquery comes with Virtuemart Component, and it is a requirement.
The second one comes with this module:
mod_logo_slider
Disable this module, OR follow this tutorial.

Then things should get back to normal.
