MergeField formatting issues

Hi

I have a working Printable which prints my quotes. However, the formatting of the numbers is not in thousand separators, so I therefore updated the Word mergefield values, but when outputting from Creatio, I get no merge values populated.This is what I have done so far:

1. Created a new version of the Word doc template
2. Toggled the field codes to display the full merge values
3. Changed a field which has a large multi thousand number from the following (note: how I have removed \*MERGEFORMAT):
   1. {MERGEFIELD "Opportunity product.Total, amount" \*MERGEFORMAT }
      
      to
   2. {MERGEFIELD "Opportunity product.Total, amount" \# #,##0.00 }
4. Uploaded to replace the working Printable
5. Generated the quote

In the resulting word doc, the values for this field are missing.

I have also tried the following variations, with none working:

{MERGEFIELD "Opportunity product.Total, amount" \# "#,##0.00" }

{MERGEFIELD Opportunity product.Total, amount \# #,##0.00 }

Either I am missing something obvious or Creatio does not like this format override.

Any help is greatly appreciated.

thanks
