This is the formula that works in excel - I cannot replicate in Smartsheet
Essential what I need is If the item in column A is in Column B return "Complete" if not return "Waiting"
'=IF(IFNA((VLOOKUP(A2,'[Win 11 Upgraded Assets.xlsx]CDN All Windows 11 23H2 Workst'!A$1:A$3700,1,FALSE))," ")=" ","Waiting","Complete")
