Issue with quotes being auto-added to variable values, breaking math calculations

I’m trying to calculate tax (price * 0.09) and display it, but the result shows the expression code instead of the calculated value.

When I set a variable value using the fx button (e.g., Number(selectedDrinkPrice) * 0.09), Axure 10 automatically wraps it in quotes, which converts the number to text. This causes all subsequent math operations to fail and display “NaN” or show the literal expression code on screen instead of the calculated result.

Is there a way to store numeric values without Axure auto-converting them to strings?
