Still trying to figure this out.
For purposes of this question "active" means NOT commented out.

There are 5 named "Trigger" Cells and 5 named Ranges.
Trigger Cell "X" is to Hide ALL 5 of the named Ranges.
Trigger Cell "1", is to hide Named Ranges 2 thru 5
Trigger Cell "2" is to hide Named Ranges 1, and 3 thru 5.
etc...............

Problem: When only ONE (ANY one) of the "groupings" is Not Commented Out,
it works great!!!
When the "ALL" group and # 1 Group are Active
Select Trigger Cell for "ALL" - Nothing seems to Happen
Select Trigger Cell for # 1 - It only Hides Group 5, NOT 2 thru 5

When Groups "ALL, # 1 and # 2" are active
Select Trigger Cell for "ALL" - Nothing Seems to Happen
Select Trigger Cell for #1 - Nothing Seems to Happen
Select Trigger Cell for # 2 - It only Hides Group Range 5, NOT 1, 3 to 5.
etc..............
Again - each one on their own works as intended.

My module "layout" is as follows:
I have a std. module I called Range_Groupings:
Sample:

Sub FB_SMI_H()
Range("FBSMINT_S").EntireRow.Hidden = True
End Sub
Sub FB_SMI_UH()
Range("FBSMINT_S").EntireRow.Hidden = False
End Sub
etc............................

I have a module I've named CALLS
sample
Sub FLBIN_ALL_H()
' Flush Bins - ALL
' ALL to be Hidden
Call FB_SMI_H
Call FB_SAI_H
Call FB_Part_MIMEL_H
Call FB_Part_MIMIL_H
Call FB_MEXM_H
End Sub

Sub FLBIN_ALL_UH()
' Flush Bins - ALL
' ALL to be UN-Hidden
Call FB_SMI_UH
Call FB_SAI_UH
Call FB_Part_MIMEL_UH
Call FB_Part_MIMIL_UH
Call FB_MEXM_UH
End Sub
ETC.........................

So:
My worksheet module makes ONE Call of my "CALL" module, which CALLS as many
Ranges as required from my "Range_Grouping" module.
This "layout" seems to give me good oversight and control of my project.
HOWEVER:
When the project doesn't work as intended, it is not of much use.

I did try moving the enableEvents true false statements around, but with no
sucess.
I am now officially desperate.
Help please ???
