Another delete user bug

[Angel]

Hey developers,

After the admin deletes a user from admin_users.php, there is an error on the page saying:


Notice: Undefined variable: validation in D:\wwwroot\SET_Apps\users\admin_users.php on line 176

Fatal error: Uncaught Error: Call to a member function errors() on null in D:\wwwroot\SET_Apps\users\admin_users.php:176 Stack trace: #0 {main} thrown in D:\wwwroot\SET_Apps\users\admin_users.php on line 176

I looked into admin_users.php and changed line 175 from this:

if (!$form_valid && Input::exists()){

to:

if (!$form_valid && Input::exists() && isset($validation)){

Now the error is gone. Please let me know if this is a bad fix.

Thanks
Angel
