Smartsheet
Excel / Sheets to Smartsheet COUNTIFS Formula
This will help you build COUNTIFS Summary Formula Fields in Smartsheet - Column A :: Notes / Purpose -> You can put the name of the Formula Field here to help - Column B :: Column with Values - Column C :: Value from Column B - Column D :: Column with Multiple Values - Column E-I :: Multiple Values from Column D -> Column E will always show up, but the others will only show if there's a value - Column J :: The below Formula
NOTE: as the image suggests, you will need to prepend = when pasting into Smartsheet. Having = in Excel / Sheets will only confuse it.
