Client Expression Help

Hi All,

7.3.0.2

Please help with client expression. Based upon values of  six columns ( A, B, C, D, E), We have to derive value of Col F

************************************

If  A=1,   Then F =  E

If A <>1 AND IF  A >= (B+C)  then F =0

If A<>1 AND IF A< (B+C)  then  F =[ (B+C)-A ]

**********************************

Thanks
