Cylinders

I keep trying to make railings with cylinders and when I compile it
doesnt work so I load up hammer again and load up my map and it says 14
solids were not loaded..........any help or how I can fix this...

your cylinder size maybe too small. When in Old Hammer ( HL1 ) if you made a cylinder too small it would not load them. So your going to have to either make it a square railing and then cut off a couple edges to make it sorta half cylinder or try increasing the cylinder size.

This is just a guess. And I am sure a more experianced mapper will be able to help you more.

My guess would be that it's too small and an invalid solid. Did you Alt-P and fix any errors in Hammer?

You'll probably have to use static prop models for this purpose, as they'll look better, will be cheaper, and won't return said errors.
