# `percentrange` (parameter type)

A range of percentages can be specified with `type="percentrange"` in the parameter definition:

>         {name="MyPercentRange", type="percentrange", default={20,80}}

The range is represented by a slider in the user interface, with two handles for adjusting the upper and lower percentages:

The current range is accessed via `self.parameters` in the `execute` method, which provides a Lua array with two Lua numbers:

>       local myPercentRange = self.parameters.MyPercentRange
>       local lowerPercentage = myPercentRange[1]
>       local upperPercentage = myPercentRange[2]
