Google Sheets Formula help: IF reference cell is BLANK, then cell is BLANK

Question

OK the solution should be simple... like =IF(AG3 = "", "") but I am unable to add the clause to my current formula as seen below: Any suggestions?

=IF(

IF(AF3 <> "y",

SUM(IFNA(VLOOKUP($AG3, RICS_TimeClocks!Q$3:U, 4, 0), 0), 
     IFNA(VLOOKUP($AG3, RICS_TimeClocks!V$3:Z, 4, 0), 0))

,"0")

 = "0", "", SUM(IFNA(VLOOKUP($AG3, RICS_TimeClocks!Q$3:U, 4, 0), 0), 
     IFNA(VLOOKUP($AG3, RICS_TimeClocks!V$3:Z, 4, 0), 0)))

Answer 1

Let's say your current formula is "FORMULA", you would have to do the following:

=IF(AG3="",,FORMULA)

Now replace FORMULA with your actual formula and you get

=IF(AG3="",,IF(

IF(AF3 <> "y",

SUM(IFNA(VLOOKUP($AG3, RICS_TimeClocks!Q$3:U, 4, 0), 0), 
     IFNA(VLOOKUP($AG3, RICS_TimeClocks!V$3:Z, 4, 0), 0))

,"0")

 = "0", "", SUM(IFNA(VLOOKUP($AG3, RICS_TimeClocks!Q$3:U, 4, 0), 0), 
     IFNA(VLOOKUP($AG3, RICS_TimeClocks!V$3:Z, 4, 0), 0))))
