    I know I could not set them, but I'm trying to write a function that will not set, or set them to blank.

    Ok people I'm trying to write a simple function that will pass a blank string back to my form when the clear button is clicked, but for some reason it will not clear my form. I can't figure this out I have written other functions that have worked, but for some reason this has me stumped. Here is my function //function to clear variables function clearVars(&$j, &$k) { $workValue = ""; $workType = ""; } $workValue = (isset($_POST['vfld']))?$_POST['vfld']:''; $workType = (isset($_POST['tfld']))?$_POST['tfld']:''; if (isset($_POST['submit'])) { if ($_POST['submit'] == "Clear") { clearVars($vfld,$tfld); } elseif ($_POST['submit'] == "Calculate") { getVars($vfld,$tfld,$calc); $continue = testVars(); if ($continue == "yes") { switch ($workType) { case "circle": calcCircle($workValue); break; case "square": calcSquare($workValue); break; case "triangle": calcTriangle($workValue); break; } } } } ?> <form method="post" action="hw06.php" id="form1" name="form1"> <p> Enter a number here : <input type="text" id="vfld" name="vfld" value="<?php echo $workValue; ?>"/> </p> <p> This number is: <br /> <input type="radio" name="tfld" value="circle" <?php if ($workType == "circle") { echo 'checked="checked"'; } ?> /> : the radius of a circle <br /> <input type="radio" name="tfld" value="square" <?php if ($workType == "square") { echo 'checked="checked"'; } ?> /> : the length of one side of a square <br /> <input type="radio" name="tfld" value="triangle" <?php if ($workType == "triangle") { echo 'checked="checked"'; } ?> /> : the length of one side of an equilateral triangle </p> <p> <input type="submit" name="submit" value="Calculate" /> <input type="submit" name="submit" value="Clear" /> </p> </form> <div id="footer"> <pre>This page written by: <cite>The President</cite> ©2011 and beyond</pre> </div> </body> </html>

    Thank you, that helped. I'm still having some issues, but I will work through them, i'm sure if it gets too confusing I will be back. What do you mean post code within [ code] ? Again thank you, it looks like you turned them into global variables? Or maybe you can explain a little more what you did?
