I am trying to call a user defined function in an if statement when the condition is true. if($number_of_rows_after>$number_of_rows_before) { myFunction(); echo "this my if"; } else{ echo "this is my else"; } myFunction() is getting called regardless of whether or not my condition is true or false so i will have "this is my else" echoed and myFuction() runs

Hi! I'm making a time laps calculator based off of the equation found http://americandslr.com/2010/10/time-lapse-calculator/ there. I'm completely done with the functional part of it. Now I need to worry about the aesthetic part of it. Here is the code: <?php if (isset($_POST['filming'])) $hour = $_POST['filming']; if (isset($_POST['framerate'])) $framerate = $_POST['framerate']; if (isset($_POST['dtrt'])) $dtrt = $_POST['dtrt']; $half = $hour * 3600; $halftwo = $framerate * $dtrt; $answer = $half / $halftwo; ?> <!DOCTYPE html> <html lang='en'> <head> <title>Timelapse Calculator</title> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <!-- Bootstrap --> <link href="css/bootstrap.min.css" rel="stylesheet" media="screen"> </head> <body> <div class="well span 5"> <form class="form-horizontal" method="POST"> <fieldset> <!-- Form Name --> <legend><h1><center>Timelapse Calculator</h1></center><br></legend> <!-- Text input--> <div class="control-group"> <label class="control-label" for="filming"><strong>Film Time (in hours)</strong></label> <div class="controls"> <input id="filming" name="filming" type="text" placeholder="type here..." class="input-medium" required=""> <p class="help-block">1 hour would be "1", 1 and a half hours would be "1.5" etc. </p> </div> </div> <!-- Text input--> <div class="control-group"> <label class="control-label" for="framerate"><strong>Frame Rate</strong></label> <div class="controls"> <input id="framerate" name="framerate" type="text" placeholder="type here..." class="input-medium" required=""> <p class="help-block">How fast will it be presented?</p> </div> </div> <!-- Text input--> <div class="control-group"> <label class="control-label" for="dtrt"><strong>Duration</strong></label> <div class="controls"> <input id="dtrt" name="dtrt" type="text" placeholder="type here..." class="input-medium" required=""> <p class="help-block">How long do you want the time lapse to last? <u>IN SECONDS</u></p> </div> </div> <!-- Button --> <div class="control-group"> <label class="control-label" for="submit"></label> <div class="controls"> <input type="submit" class="btn btn-primary btn-large" value="Submit"/> </div> </div> </fieldset> </form> <h2><center><strong><?php echo $answer . " seconds between picture" ?></center></strong></h2> </div> <script src="http://code.jquery.com/jquery.js"></script> <script src="js/bootstrap.min.js"></script> </body> </html> (yes i'm using bootstrap) Here is a screenshot of what it looks like before and after you submit: Before submission: http://gyazo.com/361d109f0af010fcda4d90288b338566 After submission: http://gyazo.com/cf1c2c2089af3f6b4bf349aeab7fc1d4 1. how do I make it round to the nearest tenth? When I used "round($answer, 1);" it crashed my script. 2. How can I make the "seconds between picture" only appear after you press submit? Thanks, I'm a noob. Fisher
