Create a new template named "error_requiredfieldaim", specify your error message when some left it blank then add this code in register.php and member.php:

PHP Code:

$aim = trim($aim);
if (!$aim)  {eval("standarderror(\"".gettemplate("error_requiredfieldaim")."\");");} 


just before :
// ENTER ANY CUSTOM FIELD VALIDATION HERE!
