# Common cases

Here are some common cases that many merchants encounter. It can be a simpler way to get you started with the module.

Each feature will have a link to the corresponding documentation page. You can find more detailed information there.

You can also find many product examples in the examples demo (opens new window)

# Examples

Create a width and height field then configure this price formula for example:

[width] * [height] * 10

But in most cases, the fields are in centimeters, so you need to convert them to meters:

[width] * [height] / 10000 * 10

In this case, you are charging 10€ for each square meter.

TIP

In the docs, Euros are used, but it depends on your shop's default currency.

You can even create a dynamic variable field called * area* and assign the area to it using a field formula.

Then you can use this variable in the price formula:

[area] = [width] * [height] / 10000

Then the price formula becomes:

[area] * 10

You can create a dropdown field (opens new window) called * material* with options like:

Then you can assign a value to each option of the dropdown and use the field directly in the price formula:

[material]

The field value will be replaced by the value of the selected option.

So it will be easy to add many options like this

[material] + [color] + [size] // etc...

You can even charge based on the area and material like this

[area] * [material]

You can use the max function to set a minimum price. For example, if you want to charge at least 10€:

MAX(10, [area] * 10)

The max function will return the highest value between the two.
