I have many different groups accessing a form.  I have several command buttons on the form.  I want to turn off some of the command buttons for three groups.  I tried using the following programming, but it doesn't seem to work. 

If @Group<>"Basic User" or @Group<>"Setup" or @Group<>"Mill"
{
     Visibility(Command1,0)
}

Is there a way to identify multiple groups and have the programming respond for each group?

If you are trying to run that code if the group is none of the listed groups, you will need to use "and" not "or".

"Or" tells the "if" statement that if any of the conditions is true, run the code. Since you are checking two (or more) "not-equal" conditions, they are always true, because group cannot be equal to "Basic User" and "Setup" at the same time, so one or both of those conditions is always true.
