The submissions are not all reaching my Google Spreadsheet

I have been sending the following form to clients who use our service - http://form.jotformpro.com/form/50484700403951

The form submissions should be recorded in a google spreadsheet in my google drive. This has been working but I believe has started to error. 

Today I received an email informing me of some of the submissions we have received. I checked the spreadsheet and unfortunately, not all the submissions had been included. On the ones that have been added, the first and second name is not getting recorded on the spreadsheet. 

Please can you advise? 

Regards,

Steve 

Hi,

Our developers were making some adjustments on the Google Spreadsheet integration recently, this might have caused the problem in your end. But we were informed that this has been resolved already.

Could you please try removing the integration and adding it again.

When you re-integrate, it will create a new spreasheet and will load all the existing submission of the form. The old spreadsheet won't be deleted but it will not anymore receive new submissions.

Please do try this and see if it resolves the problem, it you experienced the problem again, please let us know and we will forward it to our developers to have it checked.

Thank you.
