server problem solved
Thanks for your response. After your input, I double checked the connection to my local server and was able to eliminate the grayed out fields. With regard to the remote server, it turns out, for security reasons, that I was set up on Godaddy's server that does not allow "backdoor" updates through Dreamweaver. So the Data Assist wizard will not work without my changing servers. But this is no problem. I will use the local server to test. Thanks for your help.
