Hi@EEdwards,
Based on the issue that you mentioned, do you want to count the Total YES/NO/NA in a row?
Could you please share a bit more about the scenario, do you have a Gallery or a Form to do this calculation?
In my scenario, I have generated an app directly based on a Table from the Excel as below:
This app has three screens by default, BrowseScreen for a Gallery to display all the items, DeatilScreen for a detail form to display the detailed information, EditScreen for an edit form to create or edit the certain item.
In the Gallery, you could inset Labels as many as you want to display the column data. In my scenario, I insert 3Labels to display the Total YES/NO/NA.
Set the Text property of the Label corresponding to the 'Total YES' as below:
Sum(If(ThisItem.One="YES",1,0),If(ThisItem.Two="YES",1,0),If(ThisItem.Three="YES",1,0),If(ThisItem.Four="YES",1,0))
Set the Text property of the Label corresponding to the 'Total NO' as below:
Sum(If(ThisItem.One="NO",1,0),If(ThisItem.Two="NO",1,0),If(ThisItem.Three="NO",1,0),If(ThisItem.Four="NO",1,0))
Set the Text property of the Label corresponding to the 'Total NA' as below:
Sum(If(ThisItem.One="N/A",1,0),If(ThisItem.Two="N/A",1,0),If(ThisItem.Three="N/A",1,0),If(ThisItem.Four="N/A",1,0))
What's more, if you want to save this total calculation into the Excel table, you could insert Button and set the OnSelect property as below:
Patch(Table1,ThisItem,{'Total Yes':Label2.Text,'Total No':Label3.Text,'Total NA':Label4.Text})
Note: Every clicking on the button in the current row of the gallery will save the total calculation result to the corresponding row in the Excel table.

Hope it could help.
Best Regards,
Qi
