RoundProgressBar gives name error

[ae92736]

Hi,
I have installed PySide2 Extensions from pip. To be exact with pip3 for python 3.8.10
When i try the set minimum value of the bar, it gives me name "maximum" is not defined error.
When i looked up the relative code, i found out that there is a basic naming error.

I think the line 203:
if self.rpb_minimum==maximum:
should be
if self.rpb_maximum==minimum:
