Zoom lens prevents me taking a photo

Turn the aperture ring to f/32 and leave it there. After that, forget the lens has an aperture ring at all. You can let the camera control the aperture in any mode except the M and A modes. In the M and A modes, you control the aperture by turning the command dial on the front of the camera, the same way you control the aperture on a lens without an aperture ring.

Try cleaning the contacts on the camera body and lens where they meet with a cotton swab lightly dampened with rubbing alcohol.

If u used to have a Pentax camera, i would recommend you buying a Pentax DSLR, because Pentax film lenses still works on Pentax DSLR. I still use some of my prime lenses on my K10D.

This is probably not the camera settings. Pentax k200D wilt only give auto-flash with just three of their own units. Sounds like you have the Bower set on Auto. Set the flash to Manual, and adjust exposure on the aperture setting with the body set to manual as well.
Note that several people have reported problems with Bower units on digital cameras (and not just on Pentax)

I found on some lenses you need to go into the menu , select settings and change av appurature setting to 2 instead of 1 .

I've got the same problem. The problem is that the lense is loosely attached to the body. What you need to do is that when you see the Av flashing, press the lense of the camera to the body and twist the lense to the left a bit. This tightens the connection. You can then take the photo.

My husband spent 1/2 hour interpreting the manual and found I had taken the aperture setting off automatic!

This can also happen when the lens have an aperture adjustment ring, and it is not set to the "Auto" setting ("A", on my Sigma)/

Read the K100D manual. Go to the Setup menu and allow for lenses with manual aperture settings.
