If your intent is to require that G28<G22 and G22=SUM(G28:G29), put those
two tests inside an AND function:
=IF(AND(G28<G22,G22=SUM(G28:G29)),G24*(G22-G21),IF(G22<G21,0,G29*G24))

Here is the formula I am using
G21=5188
G22=10
G24=.12
G28=5188
G29-1556
=IF(G28<G22=SUM(G28:G29),G24*(G22-G21),IF(G22<G21,0,G29*G24))

Why does the statement start false and turn true? If it starts false
shouldn't it stay false no matter what the rest of the logical test says? So
what kind of logical test do i need to write so that if either part is false
then the statement is false?
