Exporting to Excel Merging fields

Hi,

I have a report with a 4 field subreport. I have aligned all fields same width and height to export. When I export 2 of my subreport fields export as merged fields.

The main report exports perfectly. If I export the subreport only it also exports perfectly.

How can I export my main report and subreport so that the each field exports to its own cell in Excel ?

Thanks,

Debbie
