How to add two values?

[DJ21]

Hello All,

May you kindly provide the formula or script for adding value?

For example, 
Row 1  of Column 1 # has value 8 and 
Row 1  of Column 2 # has value 4

How to bring 12 value through Qlik formula?

[Or]

Field1 + Field2 (+ Field 3 etc)

If some of these values can contain nulls, it is better to use RangeSum(Field1,Field2,Field3) etc

In reference to a specific formula within a table, you can also use

Column(1)+Column(2) etc
