fluidstudios

Bit of a strange problem - I have created two identical websites on different hosts and they both have 3 email forms which do work but not always.  I have tested them 5 times today and only recieved emails from them on 3 occasions. The two websites affected are www.fluidstudioswms.com and www.hertfordshire-web-design.co.uk I am not very good at PHP but can't see anything wrong so it may not be a code problem at all but not sure what else to try.  The code for one of the three forms is as follows: HTML: --------------------------------------------------------- <form method="POST" action="callback.php"> <input type=hidden name="recipient" value="mail@fluidstudioswms.com"> <input type=hidden name="subject" value="Call back">                             <p><font size="2">Your name:</font><br>                             <input type="text" name="q1">                             <p><font size="2">Telephone number:</font><br>                             <input type="text" name="q2">                                                      <p><font size="2">Preferred time/day for us to call:</font>                               <em><font size="2">(9.00 to 5.30 - monday to friday)</font></em><br>                               <input type="text" name="q3">                             <p><font size="2">Interested in:<em> (main interest                               if more than one)</em></font><br>                               <select name="q4">                                 <option value=webdesign selected>Web Design</option>                                 <option value=printing>Printing</option>                                 <option value=seo>Search Engine Optimisation</option>                                 <option value=other>Other</option>                                   </select>                             <p> <input type="submit" name="submit" value="Submit"> </form> ----------------------------------------------- PHP ----------------------------------------------- <?php // get data $EmailFrom = "mail@fluidstudioswms.com"; $EmailTo = "mail@fluidstudioswms.com"; $Subject = "Call back"; $q1 = Trim(stripslashes($_POST['q1'])); $q2 = Trim(stripslashes($_POST['q2'])); $q3 = Trim(stripslashes($_POST['q3'])); $q4 = Trim(stripslashes($_POST['q4'])); // validate $validationOK=true; if (!$validationOK) {   print "<meta http-equiv=\"refresh\" content=\"0;URL=thanks.html\">";   exit; } // prepare body text $Body = ""; $Body .= "call back!
