Error at Step 3...Cannot find SQL file

[invadertim3]

Okay, so I'm trying to install a template I got, and I passed step 2.

 

New Installation

Database Import

A test connection made to the database was successful.

Please continue the installation process to execute the database import procedure.

It is important this procedure is not interrupted, otherwise the database may end up corrupt.

The file to import must be located and named at:

/install/oscommerce.sql

BUT, when I click "continue", it comes up with this.

 

New Installation

Database Import

The following error has occurred:

SQL file does not exist: /install/oscommerce.sql

I have the install folder with the 'oscommerce.sql' file in it, but I don't understand why this error is still coming up. Can anyone help/explain please?
