complete sheet for different month and different payout

This sheet is used for additional payout.
Cell C14 used to change date for any month; Conditional formatting fail when change
Cell L6 use P57:P59 select region fails when changed; Conditional formatting fail when change

VLOOKUP(C14,Region,1,0) D14:D44 
after change VLOOKUP(C14,#NAME?,1,0) after change never turns on ConditionalStype_1
	

VLOOKUP(C14,Region,1,0) F14:F44 turns on ConditionalStype_2

Added my sheet and described my formulas.

steps to reproduce:
- allow macro execution: Tools/Options/LibreOffice/Security/Macro Security
- allow VBA Macro execution: Tools/Options/Load/Save/VBA Properties 
- restart LO
- open spreadsheet
- select "SR" from cell L6
- macro "Worksheet_Change(Range)" starts

it seems adding the already existing named range "Region" with 
the new range causes lo to invalidate the conditional formula:
VLOOKUP(C14,#NAME?,1,0) 

i am not familiar with excel vba macro's but this seems to work for me:

'   ThisWorkbook.Names.Add Name:=RangeName, RefersTo:=cell
    ThisWorkbook.Names.Add Name:="tmp", RefersTo:=cell
    ThisWorkbook.Names("tmp").Name = RangeName

first add a new named range "tmp" pointing to the new range,
then rename it to "Region".

i tend to say this is not an lo issue.

please ignore this, seems not to work

maybe changing the cell reference will help:

Rem  ThisWorkbook.Names.Add Name:=RangeName, RefersTo:=cell
ThisWorkbook.Names("Region").RefersTo = "=Input!$B$4:$C$23"

Rem  ThisWorkbook.Names.Add Name:=RangeName, RefersTo:=cell
ThisWorkbook.Names("Region").RefersTo = "=Input!$B$4:$C$23"

Does not really help using LibreOffice Calc but at least VLOOKUP(C14,#NAME?,1,0) ,#NAME? is now Region but still does not update.
Works perfect using Excel.

It seems the problem not updating the vlookup formula is also know in bug 122394 as you sent me. 
Please enplane in more detail this and how to use lo api using my example.
btw.:
the problem does not happen if named ranges content is changed via lo api,
see "test_vlookup_changed_range.ods"

(In reply to Heinrich Padrutt from comment #7)
> Please enplane in more detail this and how to use lo api using my example.

you can for - example change - the macro code like this:

If ChRange = "DS" Then
 ThisComponent.NamedRanges.getByName("Region").Content = "$Input.$B$4:$C$23"
 Else
  If ChRange = "SR" Then
     ThisComponent.NamedRanges.getByName("Region").Content = "$Input.$H$4:$I$23"
  Else
     If ChRange = "TI" Then
       ThisComponent.NamedRanges.getByName("Region").Content = "$Input.$M$4:$N$23"
    End If
  End If
End If

but as mentioned in issue https://bugs.documentfoundation.org/show_bug.cgi?id=122420 it seems the vba "worksheet_change" listener is lost.
so you need to do the code change with excel.

if you want to work with LO IMHO the best solution would be to exchange the vba code with LO basic code an save with ods file format.

Hi Oliver,
Do you think this is a valid bug ?

(In reply to Xisco Faulí from comment #9)
> Do you think this is a valid bug ?

i think if:

>  ThisWorkbook.Names("Region").RefersTo = "=Input!$B$4:$C$23"

will keep the formula valid (still pointing to "Region") we can not call it a bug, cause removing a named range will make references invalid.

the main problem seem to be the missing formula update as described in issue:
Bug 122420 - FILESAVE: VBA Worksheet_Change Listener lost on saving .xlsm in LO

Closing as dupe of bug 122420 then
