Welcome to B4A!!!
Ok, a few things, first, when you post code you better enclose it using the [ code] ... [/ code] tags or upload your project, to do that open the designer, then click on File --> Export as ZIP.
Looking at your code I see some issues, these 2 lines:
PBar.Initialize("PBar")
PIDLst.Initialize("PIDLst")
If you have created the views in the designer you DON'T have to initialize them, you only do that when you create them programmatically.
Posting the full source would help us to help you.
