"Server Error" when I try to cancel an order in Dawn 3.0.0

[ValerieD]

I am in the testing phase.  When I try to cancel and order, I get a server error.  It still cancels the order and returns item(s) to inventory.  I am concerned what might be happening in the background that is important.  

I did create a customized product template for a few of my products to add an input field because there are not enough options for some of the products (only 3?  really?)  I have no idea how to troubleshoot this.

Thank you for your help.

I am a newbie and have basically no coding experience, just watched a video on how to add an input field on the product page.  I have tried to take out the coding I added but am still getting the error.  Has anyone had an issue where they go a 'server error' when they were trying to cancel an order in Dawn?  I get the error message right before I get the message 'order cancelled'.

Thank you for your help.
