Remove / Format Date & Time in email to customers

HI,

Can someone help me? See below the email i generate via send grid. I take the date from the form and place it in my email header yet i get all the extra stuff like time and gulf standard. i just want basic date.

I have a code for it below but it doesnt appear to work? can some one tell me where im going wrong is the code to format the date in the wrong place or something as this code works fine to format a date in my other forms with repeaters.

Thanks

Dan
