Thanks for the suggestion, but it didn't work.... I got this when I clicked save.

The following template conditional expression contains function calls:

<if condition="strpos($_SERVER['HTTP_USER_AGENT'],'Googlebot') !== false">

Function Name Usage in Expression
strpos strpos($_SERVER['HTTP_USER_AGENT'],'Googlebot')

With a few exceptions, function calls are not permitted in template conditional expressions. Please go back and re-write this expression.

The following functions are allowed in template conditional expressions:
in_array() is_array() is_numeric() isset() empty() defined() array() can_moderate() can_moderate_calendar() exec_switch_bg() is_browser() is_member_of()
