At the moment I am getting an error when trying to use this function. What can I do for it?
=SUMIFS([Hours Left]@row, [Assigned To]@row, "Person's Name", [Due Date]@row, ">="&DATE(2023,8,1), [Due Date]@row, "<="&DATE(2023,8,31)
Looks like maybe you are using Excel syntax instead of Smartsheet syntax. Try this:
=SUMIFS([Hours Left]@row, [Assigned To]@row, "Person's Name", [Due Date]@row, >=DATE(2023,8,1), [Due Date]@row, <=DATE(2023,8,31)
ref must be one of: categoryID, siteSectionID, category, category/categoryID, category/name, category/description, category/url, category/allowedDiscussionTypes, locale, siteSection, siteSection/basePath, siteSection/contentLocale, siteSection/sectionGroup, siteSection/sectionID, siteSection/name, siteSection/description, siteSection/apps, siteSection/attributes, layoutViewType, discussionID, commentID, page, sort, discussion, discussion/name, tags, breadcrumbs, discussionApiParams, serverDraftID, serverDraft.
