This product uses Formulas (on STEP 2: WINDOW DIMENSIONS) to calculate prices dynamically based on your selections.
When you enter values such as width and height, APO automatically applies a formula that multiplies them by a constant and rounds the result: Round(Width × Height × 0.0689, 0)
Here’s how it works:
The total area (Width × Height) defines the size of your curtain. The constant (0.0689) represents the price per square inch. The Round(…, 0) function rounds the result to a whole number, giving a clean, precise price.
Every time you change the values, the price updates instantly - showing exactly how much your custom curtain will cost.
