You are a bit new! :grinning:

Read the instructions for posting regarding how to show your code.

Now you need to explain everything about your intended project - what a "BV20" is, how you propose to use it and what these lines could possibly mean? :astonished:

Ah! some possible further information!

That is a pretty useless site for posting images as it obscures the images in order - presumably - to promote its advertising. :roll_eyes:

Please do not be rude by putting "Help" or "Urgent" in subject titles here.
