Newb here trying to build a form that works with ints to count how many red shirts die in a classic episode of star trek (exercise to get better with forms and ints). I have an error which reads as '7 Error message: Undefined index: rsTot'. I have tried a few things and read that setting it(casting it?) as a float was the safest way to work with the int, however each thing i've attempted results in some sort of error so after a day of reading and trying i'm very confused and hoping for an answer I can understand here. I have read through stackOverflow for an answer but not seen one which i can understand and apply that speaks to the problem i'm having of initially entering and process a number as an int which i can later do some math on. error can be seen here: http://zephir.seattlecentral.edu/~jstein11/itc250/z14/w03c0102_OOPform/w03c0102_OOPform.php <?php //w03c0102_OOPform require '../inc_0700/config_inc.php'; #provides configuration, pathing, error handling, db credentials //END CONFIG AREA ---------------------------------------------------------- $rsTot = (float)$_POST['rsTot'];// float more forgiving int $rsSurvived = (float)$_POST['rsSurvived']; $rsSum = $rsTot - $rsSurvived; $rsRatio = 0; # Read the value of 'action' whether it is passed via $_POST or $_GET with $_REQUEST if(isset($_REQUEST['act'])){$myAction = (trim($_REQUEST['act']));}else{$myAction = "";} switch ($myAction) {//check 'act' for type of process case "display": # 2)Display user's name! showName(); break; default: # 1)Ask user to enter their name showForm(); } function showForm() {# shows form so user can enter their name.
