Features ​

Similar to the attribute names section, this section will display product features. The value of each field will contain the value of the corresponding product feature.

Hidden fields ​

changed ​

The module provides a field with the name changed which holds the name of the field that the customer changed in order to trigger the calculation

This field is also available in php, via the variable $changed

It's useful when you want to change the value of a field only when a specific field is changed.

Example: If the width is changed, set the height to double the width

js
[height] = IF( "[changed]" = "width", [width] * 2, [height] )

step ​

You can create a field called step to use it to control the selected step.

Make sure to give your steps a unique name each.

Example: If the material picked is wood, then jump to step 3 called color, otherwise don't change the step

js
[step] = IF( "[changed]" = "material" & "[material]" = "wood", "color", "[step]" )
