I installed openbox and want to run it independently but can't get it to run in form it seems. Any ideas how to run it by it self?

Your post is a bit confusing. Do you mean that you want openbox to be the default WM? If so, then type xwmconfig at the command prompt and choose openbox. The next time you type startx openbox will launch. I may have read your post wrong.

I think you need to chose 'openbox-session' from xwmconfig.

Openbox doesn't show up in there ( I installed from source code from there site not through the slackbuild should I use the slackbuild? How would I use the slackbuild for a 64bit installation?

but i want it to be running as lightweight as possible so I don't want it running ontop of KDE or GNOME cause this computer has 2GB of RAM and he's probably gonna use it to play games and such so I want to limit usage of RAM from other programs much has possible. Thanks guys from the help so far I thought it be done the same way but it seems to not be working

Fluxbox is just as useful as a lightweight WM and it comes as a ready made package with Slackware. If you have done the full install then you can just choose it from xwmconfig.

If you insist on openbox then use the slackbuild and chose 'openbox-session' from xwmconfig.

Agreed. It is always best to install a package using a slackbuild script as the package will work properly on your Slackware station. It is far easier to remove a package installed using a slackbuild script than a source tarball. I prefer Fluxbox when I need a light weight WM. I would try out the slackbuild script at slackbuilds.org for openbox.

Use the slackbuild. That is what I did and all works fine. Then you will be able to use xwmconfig.
