Shopify payment error at checkout -"Amount to pay must be greater than 0."

[kperson913]

I am offering a pre-sale item that will not require upfront payment, but I want to capture all order details and keep track of stats.  I am getting the following error when I test my checkout process.

I have added a third party payment vendor to hide payment options and that is working correctly. 

I have added manual payment methods to accept pay in person or pay before shipping and that is also working, but when I attempt checkout it tells me that the amount to pay must be greater than 0.

I think I need to modify the code to allow for 0 balance but not sure.

I have attached a copy of the following code files for review:

• product-template.liquid 

***Here is the Cart-template.liquid code because it would not attach****Thank you

Optional, loop through custom product line items if available

Line item properties come in as having two parts. The first part will be passed with the default form,
but p.last is the actual custom property and may be blank. If it is, don't show it.
