Function that loops through the sheet - google-apps-script

Question

I'm trying to make Apps Script macro that will do following:
Check if checkmark (cell value = TRUE/FALSE) is ticked in column A
If it's ticked, increase value of cell in column H
Repeat until reached the last row.
After a little bit of digging around in documentation, I came up with this, and from my understanding it should be working, but since I'm asking a question here, it obviously does not. Script does get executed without errors, but it changes nothing on the sheet.
function increment() {
var ss = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
var EndRow = ss.getLastRow();
for (var i = 2; i <= EndRow; i++) {
var Cell = ss.getRange(i,8);
var CheckmarkCell = ss.getRange(i,1);
if (CheckmarkCell.getValue() == 'TRUE') {
ss.Cell.setValue(ss.Cell.getValue() + 1);
}
}
}
Anyone has any idea, what's wrong here?

See if this helps?
function increMentWhenTrue() {
const sh = SpreadsheetApp.getActive().getSheetByName('Sheet1').getDataRange().offset(2, 0)
const values = sh.getValues().map(r => {
r[7] = (r[0]) ? (r[7]) ? r[7]+1 : 1 : r[7];
return r;
})
sh.setValues(values);
}
Change the sheet name in the first line to suit your requirements.
Same code with if-else statements
function increMentWhenTrue() {
const sh = SpreadsheetApp.getActive().getSheetByName('Blad1').getDataRange().offset(2, 0)
const values = sh.getValues().map(r => {
if (r[0]) {
if (r[7]) {
r[7] = r[7] + 1;
} else {
r[7] = 1;
}
} else {
r[7] = r[7];
}
return r;
})
sh.setValues(values);
}
