[Installation issue, php error]

Hello guys,

I am trying to run phpvms, I have followed instructions strictly

and I get a php error when I try to run the installation.php.

here is my error : Parse error: syntax error, unexpected '.', expecting '(' in /homepages/5/d354628588/htdocs/xav/xacars/install/install.php on line 63

here is the function that seems to generate this error :

if(!Installer::AddTables()) line 61

{ line62

echo '<div id="error">'.Installer::$error.'</div>'; line 63

break; line 64

} line 65

Thank you for your help !
