3.7.3 to smf 1.1.8

[potato]

im trying to convert

Sorry, the database connection information used in the specified installation of SMF cannot access the installation of vBulletin 3.7. This may either mean that the installation doesn't exist, or that the MySQL account used does not have permissions to access it.

The error MySQL gave was: SELECT command denied to user 'swidr_smfforu'@'localhost' for table 'user'

What does that mean

[ThorstenE]

the MySQL user from SMF (is defined in Settings.php) must be allowed to read the vBulletin database.
Common conversion errors.
