 Hi,

 

I have a table that shows an ID and two numeric variables, as in the example below:

IDVAR1VAR2
ID12010
ID22111
ID32212

 

I have to add in this table an other column (e.g. TOT) that calculate the difference between var1 to the first row and var2 to the second and so on, as in the example below:

IDVAR1VAR2TOT
ID120109
ID221119
ID3221222

 

Could anyone help me?

Thanks for your assistance.
