problem with contact form

Hello,
i bought your template and i am very satisfied except from one thing the contact form does not sent the message to the email, when i wrote something in the contact form in the message box doesnot sent it in the email. when i change the template in the contact category and i put the default of joomla it is playing correctly and sent the message. So i thought that it is problem of template please help me. iam refering the kavalatours.gr

What version of joomla do you use?

Joomla! 1.7

Do you have /html/com_contact/ folder in template folder? It is strange because we don't have contact override for HOT Designnow 1.7 . If you have it and remove it from there it will use joomla default contact.

i have the folder com_contact and i have not removed it. but when i undrerstood that i can not do anything else to play correct i try the default joomla contact form and played correctly. any other idea?

If you don't have override then joomla default is used, I have no idea then why it works with other templates ? ... Are you sure this is correct. When you say other templates that means same joomla instance???
