Good question--
Just like Jeff said, put a Print module after the DXLinks and see
which one is not producing any output.

Thanks David,
I did some more digging: I think the problem is not at the Compute end,
but rather at the DatasetTimestep end. Compute needs to compute something
from something it does not appear to get.
So...going upwards:
DatasetTimestep is a macro that is called in various places. The imputs
are a bunch of receiver objects. The transmitters (to these receivers) are
all getting data from a DXLink object. DXLink documentation state that it
is an application...
If all of this is right, and my thinking is right (a long shot), is there a
way to find which application is suppose to feed the DXLink ??
Thanks again,
Éric

Eric,
This is going to be next to impossible for anybody to help you with.
The expression supplied in the Compute module does not exist,
therefore it doesn't know what to do. We could suggest some
expressions, but I hate to say that I'm positive we'd never get it
right. For example just try setting the expression to "a" w/o the
quotes.

Hi,
I am a new DX user, I got to it 2 days ago.
I have to use a fairly complex .net program that somebody else wrote in
3.1.4, I am using 4.1.0 on a Sun box. I have next to no knowledge of DX.
The program does not run properly, I keep getting the following error in
the Message Window:
------------------
ERROR: DatasetTimestep: EnclosingTimesteps: SecondsDifference: Compute: Bad
parameter input 0 used in expression and supplied as NULL
------------------
I can get to the Compute tool in the SecondsDifference.net macro, but I'm
stuck there.
Any help appreciated, thanks in advance.
Éric
