Thank you. I've since determined that the behavior changes depending which browser I use; Chrome, Edge, or Firefox.
Button in Gallery1:
Set(currentOp, ThisItem.opNumCDS);
Reset(Gallery2);
UpdateContext({expanded: true}); //This is for visible properties
Gallery2.Items :
Sort(Filter([@hydInstructions],AssyNumCDS = Assy, updated = 'updated (hydInstructions)'.Yes),opNumCDS)
Gallery2.Default :
LookUp(Sort(Filter([@hydInstructions], AssyNumCDS = Assy, updated = 'updated (hydInstructions)'.Yes), opNumCDS), opNumCDS = currentOp)
I have label's to print currentOp and Gallery2.Selected.opNumCDS. They are both Number type.
In Edge: When I use the button in Gallery1 it disappears, Gallery2 appears. currentOp label shows me the correct number as selected, my Gallery2.Selected.opNumCDS flag is blank. Gallery2 shows me whatever record I was last looking at, it seems the Reset does nothing. I have another button that is just Reset(Gallery2) and it does nothing when I'm in Edge.
In Firefox: Same except it always Resets the Gallery to the first record of the Items property. The reset apparently doesn't like the gallery2.default property. Label for currentOp is correct, Label for Gallery2.Selected.opNumCDS shows up but always shows me the first record of the Items. So it's at least showing me that the gallery reset to the first record.
In Chrome: The button in gallery1 swaps the visible and defaults to the 6th record of the source! I haven't changed anything going from browser to browser. If I have gallery2 showing and I hit my Reset(Gallery2) button it sends me to the 6th record regardless of what's in currentOp or which record I have selected for Gallery2 or Gallery1 for that matter. EDIT: I closed out and reopened and it went back to defaulting to the First record, not the 6th.
I'm baffled. How is the behavior between browsers so dramatically different?
Side note for Firefox, you apparently can't hide gallery scroll bars, no problem in edge or chrome but that's a different issue.
