variable adding and isset not working

[viveleroi0]

I have a dynamic javascriupt form that submits the following to php:

index.php?age1=1&age2=2

and this code checks to see if the variables are set:

if(isset($age1))
  {
$Ages="$age1";
  }
					elseif(isset($age2))
  {
$Ages .= ", $age2";
   }
									else
{
}

But it never reads further than $age1 no matter what. Any ideas why (isset($age2)) is always false?

Because you're using elseif instead of just if...
