So what I am trying to do is that when I open a specific record, a popover button on another layout should become disabled and its Normal fill color should change. This to make clear that this popup button should no be used in this record.
I don't have much program experience, but from my basic programming days when I was younger, I would do something like this:
current record is (for example) record 3
disable this popover button
fill color is 8E8E8E
But I am sure that this isn't correct. How would this be formulated in Filemaker?
And I assume this calculation should be placed in the Conditional Formating field of the popover button?
