Collection based on Sharepoint List and an document library

Hi

I have a list of student in a SPList.  There is a number column is "ProfilePictureID"

I have students profile pictures in a document library with the ID being the connector to the SPList column "ProfilePictureID".

 

I already have a collection of the students to give me just the ones currently on the course.

ClearCollect(ColStudentsInTown,Filter(LongTermStudents,ProgramStartDate<=Today() And ProgramEndDate>=Today()));

I wish to make a collection of the Profile pictures just for these students. 

Basically I want to being in only the images off the document library that are needed.

I have tried this without success.  I think I need a ForAll formula??
ClearCollect(ColProfileImage,Filter(ProfileImages,LookUp(ColStudentsInTown,ProfilePictureID=ID)))

Hi @StuCundy ,

Maybe something like this

 

Clear(ColProfileImage);
ForAll(
   ColStudentsInTown As MyImages,
   Collect(
      ColProfileImage,
      Lookup(
         ProfileImages,
         ProfilePictureID = MyImages.ID
      )
   )
)

@StuCundy Use this formula:

 

Clear(ColProfileImage); ForAll(ColStudentsInTown As Student, Collect(ColProfileImage, Lookup(ProfileImages, ProfilePictureID = Student.ID)))

 

ForAll function in Power Apps

@ganeshsanap ,

Pretty much what I said . . .

Highlighted

@WarrenBelz Yes. But, I think there is some syntax error in your formula. I guess you are missing one comma(,) in your formula. 

Highlighted

@ganeshsanap not sure where

Anyway @StuCundy I think this will work for you.

@WarrenBelz Inside ForAll() and before Collect function.

Hi Guys

@WarrenBelz @ganeshsanap 

Thanks for your wisdom.  I entered the formula and get an error.

 

 

Clear(ColProfileImage);
ForAll(
    ColStudentsInTown As Students,
    Collect(
        ColProfileImage,
        LookUp(
            ProfileImages,
            ID = Students.ProfilePictureID
        )
    )
)

 

Just to clarify, ProfilePictureID is a number column in the SPlist and this = ID in the document library.
My Student list is actually called LongTermStudents but I assume that is not an issue here as we are just making a virtual list for the purpose using "As". 

 

Now I am Creating the Collection ColStudentsInTown just before this command so is there enough time maybe?

 

My total formula is 

 

ClearCollect(
    ColStudentsInTown,
    Filter(
        LongTermStudents,
        ProgramStartDate <= Today() And ProgramEndDate >= Today()
    )
);Clear(ColProfileImage);
ForAll(
    ColStudentsInTown As Students,
    Collect(
        ColProfileImage,
        LookUp(
            ProfileImages,
            ID = Students.ProfilePictureID
        )
    )
);
Set(
    ShowThisStudent,
    false
)

@StuCundy ,

What is the error?

Hi @WarrenBelz 

When I hover over the Lookup area is says that 'ProfilePicture' column doesn't exist.

Yes I did once have a column called ProfilePicture in the Sharepoint list but now only ProfilePictureID.

It is still trying to reference the deleted column....
