General Support: Not writable by the Web server.

Ok so first off im using vDeck & PHPmyadmin and really have no idea what im doing :) which isnt a good start...

anyhow I install a new database on my website give my user all permissions possible... and then run the _install.php script and I get the below errors

* The path /FilePath/ is not writable by the Web server.
* The path /FilePath/thumbs is not writable by the Web server.
* The path /FilePath/images is not writable by the Web server.
* The path /FilePath/uploads is not writable by the Web server.

Anyone had this problem before?

I came to the conclusion that its a permissions problem but cant see to work it out... So if someone knows a solution that would be great

Thanks for your help!
Cheers
