Hello and good morning Power App community,

So far the new year has been great thank God!
I hope things are going well for you as well.

My first post this year revolves around populating a person/group field with the default user that is logged in.
I have a field called "Requestor" and this field is pre populated with the current user: { DisplayName:User().FullName, Claims:"i:0#.F|membership|" & Lower(User().Email, Email: User().Email, Picture:""}

I also have another person/group field called "Request for Other"
What I would like to do is display the current user only if the "Request for Myself" (Y/N) toggle is set "Y" and set it to blank, Null or "" if the "Request for Myself" is set to "N".
I was playing with the formula IsBlank If(IsBlank(DataCardValue3.Value, do something, dont do something)) but it doesnt work.

At first glance the IsBlank is not quite right due to brackets. If(IsBlank(DataCardValue3.Value, do something, dont do something))

next thing is DataCardValue3 a toggle, dropdown or combobox

do you have screenshots of everything you are trying to filter by as IsBlank is not what i would use for a toggle.

The toggle is a Y/N field
I have two data cards
Datacard1 = current user name and only visible when the toggle is set to "Yes"
This field defaults to the current user
Datacard2 = a manual person entry field and only visible when the toggle is set to "No"
If the toggle is set to "No" then clear the Default value from DataCard1 else, dont change anything.

is DataCardValue3 the name of the toggle? if not change the below to be the name of the toggle.

change requestor which i believe is DatacardValue1 to default to
If(DataCardValue3.Value,{ DisplayName:User().FullName, Claims:"i:0#.F|membership|" & Lower(User().Email, Email: User().Email, Picture:""})

make the visible of the DatacardValue2 into
!DataCardValue3.Value
please remember i have assumed your toggle is called DataCardValue3 if it isnt try my suggestions but replace DataCardValue3 with the correct name for the toggle.

Let me know how this goes 🙂

I may have caused some confusion so I am clarifying now.
The Y/N field is DataCardValue3

The "Requestor" Person/Group field is DataCardValue6
Currently "DefaultSelectedItems" for DataCardValue6 is set as follows.

The "Request for Other" is DataCardValue14
