I just tested in 2018 myself, and I am able to export the report to Excel as long as I remove both of these options.  These options are present in reports that include the "...by Period" naming in their original title.

Timeslips 2018 is no longer eligible for direct support from Sage, so you would need to engage with a consultant such as Nancy, who has responded previously in this forum, for support as needed.

This same limitation is included in current versions of the Timeslips Premium software, as well.

thanks for your response. im still having no luck, even with those options unchecked... anything else i can try?  thanks in advance
