Birthday Emails

Birthday Emails

Hi All, 

im using the Schedules section to create a script that will automatically email clients on their birthdays with a short message. ive set it up as per the instructions in the help section but it isnt working. heres what my script looks like:

When to do:
Birthday Notification
{
Execute on Contact.Birthday at 18:30:00  yearly 
}

What to do:
sendmail
(
    To       :  input.Email_Id 
    From     :  zoho.adminuserid 
    Subject  :  "Happy Birthday" 
    Message  :  "Dear&nbsp;" + input.First_Name + "<br>\nHappy Birthday<br>\nLove,&nbsp;<br>\nKelly" 
)

can anyone tell me where ive gone wrong? 

thanks!

mel :)
