How to capture null value in following example

[kamalqlik]

Hi Friends

                 I am using the four fields as Revenue,Expenses,Tax and Year in the table.

                 We are using a expression Income as (Revenue -Expenses-Tax) ,there is one null value in tax.What i want is that when we run a loop and as it identify the null value,the loop breaks and calculate the income for the data before the null value and will show the income for the data after the null value as 0.

I am attaching my excel sheet with this.

Thanks in advance

Hi Kaushik

I just want that in a straight table the data should be displayed with calculations upto the row where the null value in Tax field is captured. You can use any other chart also.

I want that Income field should show  0 as soon as the null value in the Tax field is captured.

Thanx.

use thee formula beelow in expression

(Revenue -Expenses-if(isnull(tax)=0,tax,0))

or

(Revenue -Expenses-if(len(tax)>0,tax,0))

Sunil's formula's are correct.

Just make sure "Tax" is with a capital, like in your Excelfile

so:

     (Revenue -Expenses-if(len(Tax)>0,Tax))
