Measure Expresssion Issue

[Rehan]

I am working on a Bar Chart with one dimension and 1 Expression. The expression is for both Dollar and Qty. There is a variable defined vToggle, 1  for dollar and 2 for Qty. My Expression is 

If(vToggle ='1',

Num(Sum(Sales),'$#,##0'),

Num(Count(Qty),'#,##0')),

Selected "Measure Expression" in Number format

I get the correct results but on y-axis I don't see a Dollar sign for Sum. 

What am I missing here.

I assume the measure is fine.
In this case, I suggest you check the number formatting. It must be in "auto" (at least in Qlik Sense).

I think ,in this case the Number Formatting must be "Measure Expression" as the format is defined in the measure.

Please try this way, it works
