Hi,
I think I've spent too many hours on my computer and just can't see why i'm getting the wrong answer displayed.

I have the following php code:
----------------------------------------------------------------
          $Under6MonthsLACode='00KC';
          $Under6MonthsLAYears = 0;
          $Under6MonthsLAMonths = 1;
          $Under6MonthsLADays = 2;
          $ServiceAAYears = 0;
          $ServiceAAMonths = 2;
          $ServiceAADays = 3;

if (
($Under6MonthsLACode == 0)
|| (($Under6MonthsLAYears == 0) && ($Under6MonthsLAMonths == 0) && ($Under6MonthsLADays == 0))
|| (($ServiceAAYears == 0) && ($ServiceAAMonths == 0) && ($ServiceAADays == 0))
)          { $HostDurationUnknown = 1;} else {$HostDurationUnknown = 0;}
       
echo $HostDurationUnknown.'<br>';

---------------------------------------------------------

This IF statement is supposed to check to see if
1. The $Under6MonthsLACode is set to 0
or
2. All of the $Under6MonthsLA... Variables (Years, Months or Days) are set to 0
or
3. All of the $ServiceAA... Variables (Years, Months or Days) are set to 0
if one of the above is true then set $HostDurationUnknown to 1.

So why when all the above are not true is it displaying 1?

I'm sure its staring at me!!

Thanks
