Establishing a MySQL database

Hello,

I installed 4.5 Stable-1.0.9 and ran the pre-install check. Everything is cool, no red errors. I also just contacted my server admin and setup a MySQL Database. However, I am sort of new to MySQL. I setup a database called "mambo" using the MySQL Hosting Server. Under the Mambo Installer I enter in the folling info:

Host Name: localhost  
MySQL User Name:  my usr name    
MySQL Password: password
MySQL Database Name: mambo
Drop Existing Tables?  no
Backup Tables?  check
Install Help Data?  no
Install Sample Data?   no

When I create the database, I really do not do anything to it.. Just default settings.. I need to read a little bit more for this.

Anyway, when I hit Next, it loads the next page but does not display anything at the bottom, it says done but with errors.
Here is the code on the page:

<form name="stepBack" method="post" action="install1.php">
	<input type="hidden" name="DBhostname" value="localhost">
	<input type="hidden" name="DBuserName" value="usrname">
	<input type="hidden" name="DBpassword" value="password">
	<input type="hidden" name="DBDel" value="0">
	<input type="hidden" name="DBname" value="mambo">
	</form><SCRIPT>alert("A database error occurred
Access denied for user: 'usrname@localhost' to database 'mambo'"); window.history.go(-1);</SCRIPT>

Any help would be most appreciative or links to some help.
Thanks

This is a MySQL error so double check your db & username & password & make sure it's running on localhost.

I will I am still waiting a response from my server admin to let me know what the host name is.
Thanks for the quick response
