Use of one variable in another variable in QlikSense

[#1]

Can I use one variable in another variable?  If  I have a variable defined as vSales= Sum(Sales) and I would like  to use another variable

vComb =$(vSales)+Expression.

Is it possible? if it is, how can I do it

Yes it is possible.

In this example I am using a variable with just a number together with an expression in another variable:

SET vCalculation = sum(Sales) * vRate;

(or do something similar in an input box)
