Hello all of my smartsheets are coming up with the message - more sheets referenced than allowed and I am not sure what to do about it as the sheets were created for me and i know they all link to a 'master' sheet and now that I've added more rows this message appears every time I open the sheet. Can someone help me out as i do not want to lose any data? Thanks
