How to find my VBA function or subroutine

[SinceV2]

In the last few years, Excel seems to like to hide my subroutines. I open developer and whether I select VBA or macros -non of my functions are displayed. They exist -the spreadsheets are making calls to the functions and they are working. But where the heck is Microsoft hiding them?

See Screenshot01.jpg: None of the options in this menu will display, or even list, the VBA subroutines in my workbook or the Excel file.
See Screenshot02.jpg: Nothing I select here will display, or list, the subroutines (functions) in my workbook or Excel file. It does show a clearcells macro that I no longer use.

Again, to be clear, the visual basic routine Tube_DP(A, B, C) is working in this spreadsheet.

Is there some option somewhere that needs to be turned on?
Screenshot03 and Screenshot04 show my macro security settings from the Excel Developer menu

This must be a "me" thing since I don't see a lot of people posting this problem.

Have you tried unhiding the personal workbook?

I found "unhide" under "view" -but it is greyed out.

Then the personal book is closed therefore use previous suggestions. In VBA use the View menu and select Project Explorer.

That function will never have been visible in the macro dialogue box, as it needs arguments passed to it.
In the VB Editor, select View & then Project explorer.

That did it! Developer>Visual basic>View>Project Explorer>Modules
Quite the path! Thanks to you and Trevor G. The left column is a bit crowded since I've got two workbooks open. I go years between doing VBA code. The example below is from 1994. I've created more in recent months, but once I closed the edit box, I couldn't find them again.
