[SM-USERS] SM_Path undefined error

[Charles J Bujold]

I'm getting the following error .  How can I correct it? Thanks

Use of undefined constant SM_PATH - assumed 'SM_PATH' in f:\squirrelmail\functions\i18n.php on line 18

Fatal error: main(): Failed opening required 'SM_PATHfunctions/global.php' (include_path='.;F:\squirrelmail\include') in f:\squirrelmail\functions\i18n.php on line 18
