Rapid Start generates an error on export

Hi all

I have come across a strange error when exporting to excel using Rapid Start.

When I try to open the excel file that is created I get this warning


If I say yes to the warning I get in Excel


going past this message all the data appears to be ok in the excel file. It also happens if I save and reopen the excel file.

I have narrowed down the fields that appear to cause the error but I can see anything unusual about them so I am not sure why they are causing an error.

Has anyone seen this before, or has anyone got any ideas what the issue might be?

regards

Ian
