Business Hours - can't quite get it to work 1

[GotToBeABetterWay]

thread705-1207464

The referenced thread is exactly what I was looking for (calculating business hours between two dates). When I run my query, the calculated hours appear, then I start getting error messages and the values disappear and are replaced with #Error.

When I debug, this is what gets highlighted:

'Initalize Start and End Date Times
[highlight #FCE94F]MyDates(1).MyHrs = DateDiff("n", TimeValue(StDt), EndTim)[/highlight]
MyDates(UBound(MyDates)).MyHrs = DateDiff("n", StrtTim, TimeValue(EndDt))

I've tried replacing the DateDiff formula with a straight number (e.g. MyDates(1).MyHrs = 8). That line still gets highlighted. MyDates(1).MyHrs seems to be the source of the error.

Any ideas on what I've done wrong?

Thanks.

Does your data contain some Null values?

Thanks for the reply.

Hmm. Checking...

No nulls. All contain a date and time value. (e.g., 7/15/2014 2:46:23 PM)

I would filter the records by half and try run your query. Continue doing this to find if it's just a number of records that cause the issue. Once you find the records you should be able to find the problem and resolve it.

Ah, very clever.

It seems I had an extra line of code in there to push to the morning of the next business day those start times that were after business hours. So only the time stamps after 5pm were causing the error.

Many thanks!

Now I just have to figure how out to mark this thread as solved...

Yes, welcome to Tek-tips and thanks for the star.

One of my strategies for resolving any issue is to chop things into smaller pieces whether it's code or records. Sometimes I start from the smallest set and begin adding and other times it's divide in halves and repeat.
