jdock1 Posted April 8, 2009 Share Posted April 8, 2009 I tried making a simple app for figuring out what the customers cash tendered was - the sale amount (I was bored, and figured my bro who owns his own business who sucks at math could use it) As I said in previous posts, I am a virgin to PHP and get all my knowledge from for dummies books and other php reference books The code seems valid to me, and I am not understanding why it isn't outputting what I want it to! Here is the code: <html> <head><title>SaleCulator</title></head> <body> <form action="calculated.php" method="get"> Sale Amount:<input type="text" name="SaleAmount" \> Cash Tender:<input type="text" name="cTender" \> <input type="submit" value="Calculate" /> </form> </body> </html> <?php $sa = $_GET["SaleAmount"]; $ct = $_GET["cTender"]; $dif = $ct - $sa; ?> & for the GET form code: <?php echo "$dif"; ?> Am I doing this entirely wrong?

Daniel0 Posted April 8, 2009 Share Posted April 8, 2009 Move <?php $sa = $_GET["SaleAmount"]; $ct = $_GET["cTender"]; $dif = $ct - $sa; ?> to the other page and then read the manual to figure out why it has to be so Quote Link to comment Share on other sites More sharing options...
