Problem with uploading customized template

Hello. I have problem uploading customized template to blogger.com. I took a template and had edited it with dreamweaver but I couldn’t upload it after that. Some error massage concerning html code is appeared. Can I create my own template and how can I upload it after that? I want to create layouts like this:

Thanks for the replay. Is there any WYSIWYG editor that i can use for blogger templates or i need to edit the code manually ?
