Made a site offline, when uploading it online, I dont get it up

Ive made a wordpress site working offline, and now Im uploading it to my ftp-server, and when its uploaded, and I visit the page, I have to install wordpress.

Ive uploaded the whole content, but when Im installing it, Im ending up with a total new page, and all my files like media, pages, post, edited set-up is not there, only a standard theme.

Can someone help me get my pre-made site be the one that runs on my online-site?

Please help ??
