Hi @DorothyBL ,
I've made a test on my side and I hope this will work for you, too.
You have to write the formula for the visible property of your attachment data card as follows:
If(DataCardValue7.Selected.Value = "Renewal",true,false)
ok, did some searching here and you are using CDS and that drop down is an Option Set which makes this a whole lot more complicated that it should be :). I don't know CDS very well but you have to reference something like the selected.value = 'Your optionset name'.Value, it's too much to explain or for me to comprehend even myself right now lol..... it's usually much easier than this but due to the CDS and option set factor it complicates this a lot. And doing this as a beginner will be very frustrating :).
Anyway, hopefully someone with option set experience will come across this and be able to help!
Sorry if this troubles you 😞 CDS is what I learned but the teacher don't tell me that CDS is complicated. Hope someone would help me. Thanks for the effort!
