Is there a way to make someone input a higher value for an equation? (like Excel does)

I have a dimension that is run by an equation, but if you put a value
lower than 10, the equation gets errors. I want to set it so the
person cannot enter a lower value than 10, and if they do, a message
will pop up telling you to enter a value greater than 10. Excel can do
this with data validation, can SW ?

 

The only way I can think of to do that would be to drive the dim with a
design table and do the validation there.

WT

 

Yes, but that would only return a value. I want a message displayed
that says "You must enter a number greater than 10"

I guess I could just put a IIF(X>10, equation here, 10)

 

Low tech approach that I use during design process - modify the text
for the dim (in the property manager) to say 'Value must be greater
than 10'. You won't be able to see the dim without also seeing the
message.
If you show dim names, you can also do it there. this won't mess up
drawing - text modfications appear in the drawing - but the downside is
that showing dim names is a system property and you can't guarantee
that everyone working on the file will be set up to make the dim names
visible.
