Thank you both. I am aware that you can't place PHP inside HTML, and I do call a PHP page using the form action tag. I just wasn't sure if requinix suggestion was PHP or JS. Thank you for the clarification.

Thank you requinix. I know it's not the .php, but I assume I place this in the .html code near where I have the datepicker script so if true, I can force the popup, else false, I just continue through the form? Timezones won't matter, this form will be submitted by local users.

I am fairly new to .php and am having some trouble trying to calculate a date. I have an .html form that uses .php to send the data from the form in an email. On the form I have a jquery calendar where the user can select the date a service is needed. The user also enteres the time the service is needed as 24 hour time. I am able to pass the data and everything works fine. Originally we didn't need the date/time to be anymore than integers. So this is how the date and time are passed in the .html: <script> $(function() { $( "#datepicker" ).datepicker(); }); </script> <input name="datepicker" type="text" id="datepicker" size="10" maxlength="10" /> <input name="req_time" type="text" size="4" maxlength="4" /> the variable $datepicker passes the date to the .php and gets entered into the email as "Date Needed" formatted as mm/dd/yyyy. the variable $req_time" passes the date to the .php and gets entered into the email as "Time Needed" formated as 0000 (integer). However, now I need to check the date and time entered and compare them to the system date. If the entered date and time are less than 72 hours from the system date, I need to force a popup message. I have the popup message working. I just have no clue how to: 1) convert the entered date/time ($datepicker/$req_time) values to a date/time that can be calculated. 2) grab the saystem date/time in a value that can be calculated. 3) determine if the entered date is 72 hours or less from the syatem date. Can this be done in .php and if so, can someone assist me? SpaceChick
