I have finally figured out how to connect to a database etc and everything looks great when viewed locally. I have tried everything and all i get online is a 500 error message, I dont understand. I am no manual coder which is why i did this in dreamweaver as I am more a designer than a programmer, but nevertheless there is a glitch somewhere. Everything seems fine, the site was defined both the local and remote were defined, so everything seems ok, but I still have this error message. Can anyone please provide me with a solution 
Thanks
