getsheetbyname with variable cell - google-apps-script

Question

I have a sheet called Audit with cell B1 corresponding to a specific shopID.
I have built a sheet with each shopID called ShopID+PrevAudit (555PrevAudit)
When they complete the audit they click a button that should copy values and format to the corresponding sheet i've created but I'm getting hung up on calling the correct sheet based on a B1 entry.
This is what I had been using but it was static and i want to make this easier on myself. I'm not sure why this is so difficult for me. Thanks for any help you can provide.
function copyaudit() {
var source = SpreadsheetApp.openById('SheetID');
var sourceSheet = source.getSheetByName('Audit');
var sourceRange = sourceSheet.getDataRange();
var sourceValues = sourceRange.getValues();
var tempSheet = source.getSheetByName('555PrevAudit');
var tempRange = tempSheet.getRange('A1:L51');
var destination = SpreadsheetApp.openById('SheetID');
sourceRange.copyTo(tempRange); // paste all formats?, broken references
tempRange.offset(0, 0, sourceValues.length, sourceValues[0].length)
.setValues(sourceValues); // paste all values (over broken refs)
}

Using a JS template string, you can generate the sheet name:
`${destID}PrevAudit`
To put it in context:
function copyaudit()
{
const range = 'A1:L51';
let spreadSheet = SpreadsheetApp.openById('SheetID');
let sourceSheet = spreadSheet.getSheetByName('Audit');
let sourceRange = sourceSheet.getRange(range);
// Get B1
let destID = sourceRange.getValues()[0][1];
let destSheet = spreadSheet.getSheetByName(`${destID}PrevAudit`);
sourceRange.copyTo(destSheet.getRange(range));
}
