TheFormulaValuestructure specifies the current value of a formula. It can be a numeric value, a Boolean value, an error value, a string value, or a blank string value. IffExprOis not 0xFFFF, the 8 bytes of this structure specify an Xnum (section2.5.342). IffExprOis 0xFFFF, this ...
MONTH(A:A) is not a range but an array. The criteria_range arguments of SUMIFSmustbe ranges, not arrays. You can use SUMPRODUCT instead: =SUMPRODUCT(C2:C1000, (MONTH(A2:A1000)=8)*(B2:B1000="Groceries")) (I'd use finite ranges instead of entire columns for reasons of perf...

First of all, I thank you for your patience and help. I downloaded the file you shared and recreated it on my own actual file. Just a question though,... What is the prefix "_xlfn." means? I think this is the keyword that's causing the syntax error. ...
tan x = 1/cot x cot x = 1/tan x What is sin 2x identity? sin 2x = 2sin(x)cos(x) The sin 2x identity is a double angle identity. It can be used to derive other identities.Trig Identities Trigonometric identities, trig identities or trig formulas for short, are equations that ...
