First,Sort,filter on a gallery Help Appreciated

[gazzo1967]

Hi

2 datasources Sharepoint lists
BA Tac vent - calendar (i now this is just a list :))
Ba Hot Wear - List

I have a gallery which is filtered by 

Filter(
ColTVCal,
    bookdate = Text(DatePicker1_1.SelectedDate))

colTVCal is a collection on BA Tac vent Sharepoint calendar.
I have 3 extra fields that are completed with 3 people picker names.
For each calendar event ID on the date selected
I return the people picker name values in 3 labels
(hope i havent lost you!!!)
Then i filter the 2nd list (BA hot Wear) to return the relevant last entry values. eg The 'ID' column
using the following formula

First(
   Sort(
      Filter(
         colHW ,
         'Candidate Name'.DisplayName = cand.Text
      ),
      ID,
      Descending
   )
).ID

colHW is a collection from BA Hot Wear list.
This should return the last recorded entry 
BUT
im getting the one before it not the latest?

HELP 🙂
Any help gratefully received
Gary
PS i bet its simple!

Yes, you are working with a collection.  A collection is a snapshot variable of the table you assign to it, at the time you assign records to it.  It will NOT update itself.  You have to constantly take the performance hit of updating your collection yourself.

I would recommend just working with the datasource and drop the duplicated data in your app.

Your formula...:

LookUp(
   Sort('BA Hot Wear', ID, Descending),
   'Candidate Name'.DisplayName = cand.Text
).ID

The above will provide the result you are looking for.

I hope this is helpful for you.

Wow Randy I only walked up the yard l and back to fetch a glass of wine (UK)
I see what you mean about the duplicated data.
Just goes to show how sometimes 'we' intermediate users over complicate the actions trying to be a smarty pants! lol

Worked perfectly thank you
