Dynamic Worksheet Name using Excel Plugin

I am using the Excel plugin to merge data into a spreadsheet.  I would like each record to be displayed on it's own worksheet.  When using the block=Worksheet parameter, I get an XML error "to many tags" which I found out with a goole search means you are attempting to create worksheets with the same names.  The XML for the worksheet tag is like this:
<Worksheet ss:Name="Summary">
I would like the name to be the result of a data merge, like
<Worksheet ss:Name=[data.RECORD_NAME]>
but I can't get the syntax correct. 

Any assistance would be greatly appreciated.

- On your Excel template, name your Sheet with a simple string which is unique, like "MySheetToMerge".
- In your application do something like this:

Hi,
I've tried this workaround, but it seems not working anymore.

Do I something wrong or is there any other solution to make this work?

I've using OpenTBS 1.8.1

Best regards,
