GoogleSheets ApsScript ReferenceError: ADDRESS is not definedDetails - google-apps-script

Question

In the following code snippet there is a very simple code.
When I try to use it I'm getting
ReferenceError: ADDRESS is not defined error.
I'll appreciate very much if someone could shed a light on this issue.
function temp() {
var spreadsheet = SpreadsheetApp.getActive();
spreadsheet.getRange(ADDRESS(15,D1)).activate;
};

Issue 1:
ADDRESS is a google sheets function but you are trying to use it in Google Apps Script.
The latter does not accept google sheets formulas. It has its own documentation and only JavaScript is supported.
Issue 2:
To execute a function in any programming language you need to add parentheses at the end of the function. Replace activate with activate().
Solution:
You most likely want to take the range of cell D15. If that's the case then simply do:
function temp() {
var spreadsheet = SpreadsheetApp.getActive();
spreadsheet.getRange('D15').activate();
};
Keep in mind this will work for the active sheet only (the sheet that is currently selected). If you want to select a specific sheet by its name, then do that and change Sheet1 to the sheet name of your choice:
function temp() {
var spreadsheet = SpreadsheetApp.getActive();
var sheet = spreadsheet.getSheetByName('Sheet1') // put the sheet name of your choice
sheet.getRange('D15').activate();
};
Updated answer based on your comment:
Assuming cell D15 contains a cell reference of the cell you want to activate, then do that:
function temp() {
var spreadsheet = SpreadsheetApp.getActive();
var sheet = spreadsheet.getSheetByName('Sheet1') // put the sheet name of your choice
sheet.getRange(sheet.getRange('D15').getValue()).activate();
};
or based on your original code:
function temp() {
var spreadsheet = SpreadsheetApp.getActive();
spreadsheet.getRange(spreadsheet.getRange('D15').getValue()).activate();
};
