Someone in my company is attempting to build an Access Web Database that includes a datasheet form.  After deployment, everything works well except the datasheet form. This form won't render.  I do see a JavaScript error "Unable to get property 'ColumnName' of undefined or null reference".  When I click on the tab with the datasheet form on it, I see several Loading messages with spinners and then nothing. The page is blank.  There is HTML inside the area where I would expect to see the form but all the containers are empty. I'm guessing because of the JS error, not sure.  Any help would be appreciated.

Hi Robbertv

Could you offer a screenshot about your issue?

Before you design a form that contains a datasheet, you should review the relationships between your tables and add any relationships that are missing. Doing this enables Access to automatically create the links between datasheets and main forms.

I refer to the following article to insert a datasheet into a form and publish it to the SharePoint 2013 and it works fine.

Take a look at it:
