ET1=If(Zone_log=4 ,If( AC>=280,If( R>=3.5,If( R4>=5.0, 1, 0) , 0) ,0 ) , 0)
wait a minute!
your code may be wrong. "If( R4>=5.0, 1, 0)" is true that can go " If( R>=3.5,If( R4>=5.0, 1, 0) , 0)"=1 or 0.
But "If( R4>=5.0, 1, 0)" is false that " If( R>=3.5,If( R4>=5.0, 1, 0) , 0)" alway is zero. In this case, your up level "if" is no meaning.
Therefore, your code is rediculous.
Suggestion: use "and" "or" connecting your conditions. |
