Dashboard Reports Unable to be viewed

edited 12/09/19 in Smartsheet Basics

I have one major sheet where I collect numerous datapoints.  I created one dashboard with different widgets - one being numerous report widgets within based on the one major data sheet.  I sent email to share my dashboard with numerous but they couldn't see any of the data within the report dashboard widget.  Only way it seems to work if i had individuals to the major data sheet - which i'd rather not do.  But if I have to I want to use a group list and not have it email inviting to the major data sheet.  How do I work around this?
