How to create new column with percentage?

[SS1]

Hi,

My search is giving below output,

Month  FieldA    FieldB
Jan         285      1410
Feb         247      1934
Mar         215      2197

Can we create a new column with FieldA% and FieldB%, below is the example

Month  FieldA    FieldB   FieldA% FieldB%
Jan         285      1410        20%           80%      
Feb         247      1934         22%          78%
Mar         215      2197         15%           85%

Eventually i will only be using Month and FieldA% in a column chart

Use eval to compute the percentage

| eval FieldApct = (FieldA*100)/(FieldA + FieldB)
| rename FieldApct as "FieldA%"
