I am looking to get the weight column in my medical log sheet to be updated automatically when I key in the new weights on my Weight Log sheet. I take the weights weekly and update the info into a new column. How could I do this? Please note I want to keep the log so I dont want to have to delete past weigh ins.

    Welcome to Web Applications Stack Exchange. Please edit your question and insert a table of sample data together with another table that shows your manually entered desired results. Also consider sharing a publicly editable sample spreadsheet. There is a blank sheet maker that lets you share safely. Jan 22, 2023 at 8:04

Use reduce() and filter(), like this:

  "", filter('Weight Log'!B$2:Z, 'Weight Log'!A$2:A = A2), 
    result, current, 
    if( len(current), current, result )
