Hi Friends, I have a requirement , In list box by pressing ctrl we can select multiple values. So i want a restriction as user can select max up to 2 by pressing ctrl.
Go to Solution.
You can do something like this:
=If(GetSelectedCount(myField)>2, 'Error', myField)
but you will see the text "Error" only when you release the CTRL button
Ya Good...But I can see error mesg any other option....
