Hi,

I am new to ESdat and am creating my first database. When I try to import sample results I get the following error:

"One or more values are prohibited by the validation rule '"<" Or ">" Or Is Null' set for 'Chemistry_Results.Prefix'.  Enter a value that the expression for this field can accept."

I am not sure what this means and I cannot find a way to fix it. Any help would be greatly appreciated.

Thanks,

Ian
