Basically I have used a formula to suppress a section if the previous row has the same data.  So I used;

{fieldname} = Previous ({fieldname})

 

I have used this on the 'details a' section.  The details are inclusive of a 'details a' and 'details b'.

 

The issue I am facing is that for some strange reason, 'details a' is not appearing for the first line and only 'details b' is showing - and this is for the first line of data only.  The details for a and b show correctly from there on. 

 

Does anyone have any suggestions or has anyone seen this happen before?

 

Thanks for your time.
