Essential Form Data Missing

Hi,

I've got a VB Web Class that I (didn't write), but support.

The majority of users are based in the office in which the web server resides, but those out in regional offices get the following message whenever they sumbit data.

Essential data form has not been received with your submittal.

I've looked at various different types of possible causes, but it doesn't seem to help. Does anyone have any idea what could be causing this problem, I doubt it would be anything to do with networks, proxy servers/firewalls etc.

Cheers,

That looks like a developer error message, not a system error message - if you have access to the soure code, search for the error message and see what has to happen (or not happen) for that message to appear.

You are correct, I don't know what I was thinking putting that up there. I do have access to source code, this is definately a developer error. Still don't know what could be causing this though, and it's still definately peculiar to off site offices.

I'm going to try and set it up so that one of the remote users tries to access a copy of this application on my local machine, and set a breakpoint at the function that raises the error, to try to find out exactly what is causing this. Any other ideas?

Cheers,

Well, you'll probably find the error in a if..then block -

IF (this happens) Then
(do this)
Else
(Display the error message)
End If


This will probably give you a clue as to why you get the error - whatever is being checked in the "IF" part of the statement.
