Hi can anyone tell me please, why this formula:

=ROUND(7/(C3-D3),5)

gives an incorrect answer, when I extend it to:

=IF(AND(ISNUMBER(C3),ISNUMBER(D3),C3-D3<0),IF(ROUND(7/(C3-D3),5)0.5,C3,""),"")

the answer should be, 604799.85862 and is when I use the first small
formula. It becomes 36891.00001

thanks,

Ted.
