Dynamically change form control value

[StuLux]

I'm not sure if I am trying to do something impossible or whether I am approaching the problem in completely the wrong way:

I have a form which is designed to be completed and printed off for signing. There is a sub-form which will detail any risks that are open and I have placed a text box that states that if there are any open risks they will be listed, if there are no risks the sub-form is empty. I would prefer to make this a bit more intuitive and have the text box categorically state when there are no risks and, if there are live risks, how many.

I'm pretty sure I need ot use DCount but can I change the value of a textbox in this way or do I need some other form of control on the form? I didn't really want to store this number anywhere.

Hi Stuart

Is each risk stored separately within another table? If so, the DCount method will be the way to go. But rather than store the outcome (even if it is zero) in a linked control on your form/report, simply include the DCount as part of a statement to the same effect in an unbound box, e.g.

=IIF(DCount(......)=0, "There are no risks", "There is/are " & DCount(....) & "open risk(s)")

I haven't tested this but have used this technique before with success.
