Google Sheets - Autosort Script issues

Question

I am trying to sort data descending based upon column B (2) which has different numbers in each cell. EG: B8 = 99, B14 = 70, etc. I'm intending for it to autosort and do it onEdit. I'm not good at coding, like at all. So I watched a YouTube vid and came up with this, but it still doesn't work.

function autoSort(e){
    const row = e.range.getRow()
    const column = e.range.getColumn()
    const ss = e.source
    const currentSheet = ss.getActiveSheet()
    const currentSheetName = currentSheet.getSheetName()

    if(!(currentSheetName === "Roster" && column === 9 && row >= 8)) return

    const range = currentSheet.getRange(8,5,21,22)

    range.sort({column: 2, ascending: false})

}


function onEdit(e){

  autoSort (e)
