When I inspected your form I did not saw PayPal payment field. Inside of this guide you can find how to set up your order form:
Error message "Sorry! Only one entry is allowed.", is related to form limits.
I have inspected setting of your form and you have set Unique submissions and Unique question limit.
This means that form cannot be submitted two times from same device of with same email address. If you want to remove limitations for submissions, set them to NoCheck.
More about submission limits based on unique question and unique submissions, you can find inside of this guides:
Hope this will help. Let us know if you need further assistance.
