When submitting a payment form it says that it's expired. I dont understand this.

Based on your form limit settings (http://www.jotform.com/help/137-How-to-Limit-Submissions-in-a-Form), you have a Warning Message that says this but the limit in the form is not set so you should not suppose to get this.

I've cleared your forms cache (http://www.jotform.com/help/229-How-to-Clear-your-Form-Cache). Would you mind trying again?

Thanks
