当我有多张图纸时，为什么getActiveCell停止工作？

Question

I am not actually sure whether it is getActiveCell or something else that is failing, but this is the code I'm having trouble with:

var dataSheet = SpreadsheetApp.getActiveSheet();
var program2define = dataSheet.getActiveCell();
var tempContents = program2define.getDisplayValue();

When I have just one sheet, this gets the string in the active cell, no problems. When I add another sheet, suddenly it gets an empty string. I've checked and double checked, I've tried using getSheetByName instead of getActiveSheet - same problem. I've tried it in a test sheet with only one cell filled - same problem as soon as I add another sheet.

When I searched, I found this but the problem is the same (empty String) even if I make sure every sheet in the spreadsheet has an active cell that is filled.

Thanks for any tips!

getActiveSheet() gets the active sheet in a spreadsheet and you can only have 1 active sheet at a time, even an active cell. So it doesn't make sense that you'd apply it in multiple sheets.
