Adding Text to Gift Certificate Form

I am trying to add a line of text that says “Postal Mail - Please allow 5-7 business days for shipment” beneath the “How to Send” option on the Gift Certificate form.

I have been trying to add this text to the update.tpl template found in skins/basic/customer/addons/gift_certificates/views/gift_certificates, but every time I try it gives me an error message that says “Error Oops, something went wrong (error). Please try again.”

Can anyone help me out on this one? It seems like such a simple thing but I can't figure out what I'm doing wrong!

At Line number 111 of update.tpl, replace the line with below:


Postal Mail - Please allow 5-7 business days for shipment
