Windscreen bolts?

Sorry for what may be a silly question but I've been searching online for ages!

Where are the bolts to ensure the windscreen is securely located?
Just got my 110 and every time I hit a pothole or uneven patch of road the windscreen on the passenger side rattles very loudly, almost like it could break! Sounds like it's not properly secure on that side, the drivers side doesn't do it though.
The rubber seal on the glass doesn't seem too bad and isn't letting in water so don't think its that.
As I've been working the last few days I haven't had chance to look in the daylight!
It's a 300tdi if it makes any difference.
Pics of my new toy to follow once I get a day off!
Thanks!

If you are talking the front screen.. Also saying that the rubber seal seems ok..I would not think it was the glass as such rattling.. pics would be a good idea so we can see where n what you are meaning.

See the aluminium block that goes between the bulkhead and the window frame (just above the door hinge). Its secured by three bolts just down the left side of the dashboard by the passenger grab handle

Thanks for the prompt replies, get an early finish from work tomorrow so shall check when I get in.
Really do appreciate the help, feels good to be part of something I s wanted to be involved in for a long time!
Hopefully someday soon I'll be able to help somebody else!
Thanks again!

And I'll post piccies soon!
