JavaScript Error: prototype.js is required

protoplus.js:34 Uncaught Error:prototype.js is required by protoplus.js. Go to prototypejs.org and download lates version.

I believe you are referring to your Product order form https://form.jotform.me/80855965150463

However, I checked your form and don't see that error anywhere.

So that leads me to believe you are embedding this form on a website somewhere right?

Can you please provide us with the link to the website? And tells us who is your web host?

Usually to resolve this problem we recommend to use the iframe embed method:
