Hidden and Empty are not the same thing. I will assume that you mean empty, not "hidden".
IsEmpty ( Get ( ActiveFieldContents ) )
would seem to be the test that you are looking for here.
I mean both. Sorry my original post must be a little confusing. I have a layout that has a bunch of fields that will hide/unhide upon what a certain field (or fields) contains. I am trying to make a more efficient script to require that all visible fields must contain some sort of import. I want to make it so if the field is empty and visible it pops up a prompt saying you must enter a value into [Blank] field. But than if it is also empty but hidden I want it to skip over it. So I am wondering if there are any script or calculations that can look at an active field and determine if its visible or not.
The only way to hide a field is to specify a Hide Object When Expression. So your check would need to use the same expression to check to see if the object is currently visible.
Ok thank you. At least I know now that the way I am doing it is the only way it can be done. Be cool to see FileMaker add scripts that can see if fields are hidden or not and can hide fields through the script.
