Google Sheets - Modify Code To Act Dynamically When Using Slice - google-apps-script

Question

I am using the splice Script to run code over numerous tabs
function Slice_TABS() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheets = ss.getSheets().slice(7); // get 8th sheet onwards
sheets.forEach(ss=>{
Donor();
})}
and am trying to use the below code to bring filtered results up to 10 per SKU. When i name the sheet the code works fine but i need it to run on the ActiveSpreadsheet. I am getting the following error
" Type Error: sheet.getRange is not a function" (BOLD Below)
function GetNSKUSAG11() {
var ss = SpreadsheetApp.getActive();
var sheet = ss.getSheets();
*//Building the matching set.
**var matchingValues = sheet.getRange('AF3:AF').getValues().filter(value => value[0] !=
'').map(nonBlankValue => [nonBlankValue[0], 0]);***
//Filtering out the desired number of values
var values = sheet.getRange("LOCATIONS!$A$3:$B").getValues().filter(value =>
advancedFilter(value[0], matchingValues));
let cols = values[0].length;
let rows = values.length;
//Printing out the found rows starting from AI
sheet.getRange(2, 36, rows, cols).setValues(values);
}
function advancedFilter(value, toMatch) {
let matched = toMatch.filter(couple => couple[0] === value);
if (matched.length > 0) {
if (matched[0][1]<10) { //Here you can decide when to stop returning SKUs
matched[0][1] += 1;
return true;
}
}
return false;
}
I think I am close.
