Unable to select the specified database

I need assistance with installing grocery crud in CodeIgniter using Wamp. I'm encountering the following error:

"A Database Error Occurred: Unable to select the specified database: archives_collection, Filename: C:\wamp\www\archives_collection\system\database\DB_driver.php, Line Number: 140"

I've checked the user and password as mentioned in the installation documentation, but the error persists. Can you please help me troubleshoot this issue? Thank you in advance!
