Hi
I been away for sometime. Pls help me with my new problem
i need to do a leave calculation using a text box.
I have a start date (date format) and number of days(number).
The calculation i can do is
lastdate=datead d("d",-1,[start date]+[number of days])
this gives the difference, but i need to minus the weekends from the total
I tried using "w" instead of "d" but no use
pls help me

For obvious reasons, this is not something that can be done with a line or two of code! I picked this function up somewhere in the past. Sad to say, I don't know who to credit for it!

Save the module and name it AddWeekdaysOnly
Since your original code was - lastdate=dateadd("d",-1,[start date]+[number of days])
what you're actually doing is adding ([number of days] - 1) so we make that the Interval.
To invoke the function: - Interval = [number of days]-1
-
LastDate = DateAddW([Start Date], interval)

I have two date fields:
-Inquiry Date
-Action Date
I'm trying to use a query expression on this.
Using the datediff expression, I can get the amount of days that seperate
the two dates. But I would like to know how I can get only a count of the
weekdays only.
I'm not sure if there is another expression I can use to get the result.
