Re: ->

Aisch! Hmmm... yep, clear as mud. Let me describe what I we have going on: We have a function called ToForm which looks like it verifies values coming in from a POST. This function is invoked like this: $generic->ToForm("cart_id", NO_DEFAULT_VALUE); $generic->ToForm("email_address", NO_DEFAULT_VALUE); I don't understand the $generic-> and what happens when it "becomes" something twice. The ToForm function looks like this: function ToFORM($val, $default, $makeuppercase=0) { global $FORM, $$val; if(!empty(${$val})) $FORM[$val] = trim(${$val}); else if($default != NO_DEFAULT_VALUE) $FORM[$val] = $default; if($makeuppercase) $FORM[$val] = strtoupper($FORM[$val]); } Thanks for the help!
