Changed WordPress address url…help

I am using network solutions as a host. Creating a word press site thru them. Have been setting up my site on word press using the url they provided. Was ready to upload and launch my site. Well I changed the wordpress address url. I followed these instructions:

http://codex.wordpress.org/Changing_The_Site_URL
Now I can not log in and the error:

Parse error: syntax error, unexpected ‘&’ in /data/23/2/128/72/2943235/user/3262192/htdocs/wordpress1/wp-includes/functions.php on line 1863

appears.

Please help. Also, any advice on how to get out of this hole and change my address from http://036cf37.netsolhost.com/wordpress1/wp-login.php to bancstartitle.com would be much appriciated.
