How do i fix the pay section

trying to create an order form- any time i click submit it says invalid paypal account- is there a way to do it without paypal? I just want to have people be able to submit the sizes- ill collect the money in person!!

If you will collect the money on person, then you should use the Purchase Order payment tool inside of the Paypal. 

Purchase Order Tool allows you to create payment forms, order forms or purchase order forms without payment vendor integration.

Simply remove the Paypal field from your form and add Purchase Order payment tool. Products that you previously added will be saved and automatically added the Purchase Order payment tool. 

Here is my demo form: https://form.jotformpro.com/72744596479980
