Calcutlating a DueDate with a working days function

[Guest]

Hi,

I think I need a little help with my dates!

I have a field: [DateLoggedIn], which stores date entry date.

I am trying to achieve in a query is an expression which creates a new
calculated field as [DueDate}. This expression is to calculate 3 working days
from [DateLoggedIn}.

I have a function called “WorkingDaysâ€, which calculates the working days
and holidays, but I am having trouble applying it to the expression. I have
entered the following:

DueDate : DateAdd("d",3,(WorkingDays([DateLoggedIn])


Unfortunately it is not working, any help would be much appreciated!
Chris.

Further clarify 'not working'. Post error messages. Give an example input
and output. etc.

Normally there are two functions used with working days. One function
calculates the difference in working days between a supplied from_date
and a supplied to_date. This functions returns an integer value.

Another type of function adds to or substracts from a provided date a
desired number of working days. This function returns a date value.
This is what you are asking for, the date 3 days in the future from
DateLoggedIn.

Assuming you had such a function , it would be something like:

DueDate: WorkDaysOffset([DateLoggedIN],3)
