problem using a function from an external library in vba

hello!

I am using an external adding that allows me to check if a given date is a business day according to a calendar. the syntax is: =isbusinessday(date, "calendar")

where date is the date and calendar can be HK, FR, UK...

the function returns 1 if it is a business day, 0 otherwise

right now I have this syntax in a For / Next loop:

[VBA]
If isbusinessdays(wsHistData.Cells(2, 6) + i, FinCenter1) And _
isbusinessdays(wsHistData.Cells(2, 6) + i, FinCenter2) And _
isbusinessdays(wsHistData.Cells(2, 6) + i, FinCenter3) <> 0 Then
[/VBA]

each FinCenter is defined as follows:

[VBA]
FinCenter1 = wsHistData.Cells(1, 3)
FinCenter2 = wsHistData.Cells(2, 3)
FinCenter3 = wsHistData.Cells(3, 3)
[/VBA]

the problem is that it returns an error (like the function is undefined)

I believe my syntax is wrong. can anyone help please?

thx

You have to check every condition, not only the third one.[VBA]If isbusinessdays(wsHistData.Cells(2, 6) + i, FinCenter1) <> 0 And _
isbusinessdays(wsHistData.Cells(2, 6) + i, FinCenter2) <> 0 And _
isbusinessdays(wsHistData.Cells(2, 6) + i, FinCenter3) <> 0 Then
MsgBox "All days are different from zero", vbInformation
Else
MsgBox "All days are zero", vbInformation
End If[/VBA]Charlize

thnks! works much better

btw: it can happen that FinCenter2 or FinCenter3 = 0 (making the loop crash)
Could you point me in the right direction in order to ignore the FinCenter when = to 0 please??

well it seems I have a problem getting the logic of this thing.

I want to get 1 column with dates
each date has to be a business day according to at least 1 calendar (max 3 calendars)
I need to get (end date - start date) iterations

this is what I have:

- a start date
- an end date
- to 3 calendars
- 2 functions: isbusinessday and forwarddate

isbusinessday returns 0 or 1 depending on whether a given date is a business day according to 1 calendar
forwarddate give the next business day if a given business day is not a trading day

I have a problem understanding how to loop correctly the thing apparently...

can someone pont me in the right direction (strategy) in order to find the business days I need accoring to 1 to 3 calendars please??

thanks
