Silently require data validation

[Quartekoen]

I have a script that is designed simply for entering data into an invoice. When it starts, it puts the user in a certain field and pauses. The user enters data and hits enter which resumes the script. They are then sent to the next field, and it pauses again. This continues until they've entered all required data. (Yes, I know about tab orders and field behaviors. This method was chosen for another reason).

Here's my problem. I had one of the users test out the system to see how it was working. He did well, but I noticed a couple times where he would accidentally hit enter twice without knowing it, thus sending him to the next field without the prior having data in it. This would 'confuse' my script. I'm wondering if there is a way to have a 'silent' form of data validation.

I know that you can require 'not empty' in validation in the field options, but when the field is left empty, an annoying warning message comes up telling them that the field is required. What I'd much rather prefer is for it to, let's say, beep, then stay in that field.

Basically, if they hit enter and the field has data, continue the script and go to the next field. If they hit enter and the field is empty, beep, but stay in that field. When data is then put in, and enter is hit, THEN continue the script and move to the next field.

I'm rather stumped by this. Any help would be great. Thanks.

Well, you are running a script already - so why not incorporate this in the script itself?

Oh, don't get me wrong, that's what I want to do. My problem is moving around in the script

If they hit enter and there's no data, it needs to beep *instead* of continuing on with the script. If I put a simple If statement in there, containing everything after the first pause, then sure, it will check to see if there's data, but then it will skip over the rest of the script, and the script will end. So my question would be: How do I sort of make a paused script continue if there's data and enter is pressed, and do nothing if there's no data and enter is pressed. I don't mean "don't continue". I mean "don't do anything. Don't continue. Just wait there until there's data, then go to the next field"

Loop

Go to Field [ Table::Field1 ]

Pause/Resume Script [ Indefinitely ]

Exit Loop If [ not IsEmpty ( Table::Field1 ) ]

Beep

End Loop

#

Loop

Go to Field [ Table::Field2 ]

changed the order slightly

Gosh, something in my mind was broken again, telling me that because I was already in a loop, I couldn't go into another one, but I'm sure this will be the solution. Thanks for coming through again.
