1. Please read the first post on this Q&A.

2. Just curious: Why use a CHOOSE CASE if you only have one case?

3. Have you debugged your code?

Just curious: Why use a CHOOSE CASE if you only have one case?

Using CHOOSE CASE because there are several reports.

Have you debugged your code?

Yes, we have debugged the code and it appeared that it should do what's expected, but does not.

What happens if you only do the SendRequest('POST' with a single attachment, trying to send the second one)?

If we choose one report to go to several recipients, it works as expected.  It will send that one report to several recipients.

The problem come in when there's more than one report to email out.  For example, if two reports needs to go to two recipients, the code will send the first report to both recipients twice.  It never sends out the second report.
