(f) script works (e) doesnt - google-apps-script

Question

i have these two scripts that do the same thing just on different pages, but the f script works and the e script doesnt, any help??
function onEdit(e) {
if (e.source.getActiveSheet().getName() !== "RS3 Points" ||
e.range.columnStart < 9 || e.range.columnStart > 35 ||
e.range.rowStart < 4 || e.range
.columnStart < e.range.columnEnd) return;
e.range.offset(0, 37 - e.range.columnStart).setValue(new Date());
}
function onEdit(f) {
if (f.source.getActiveSheet().getName() !== "OS Points" ||
f.range.columnStart < 6 || f.range.columnStart > 37 ||
f.range.rowStart < 4 || f.range
.columnStart < f.range.columnEnd) return;
f.range.offset(0, 39 - f.range.columnStart).setValue(new Date());
}

Answer 1

Munkey's intuition is right. You can't have more than one onEdit() in the same project. Moreover 'e' is not a random letter (that can be replaced by any other letter) but stands for 'event object'. You can read more about that here. The solution would indeed consist in 'merging' the two scripts into one. Give this a try:
function onEdit(e) {
var ind = ["RS3 Points", "OS Points"].indexOf(e.source.getActiveSheet()
.getName()),
startCol = [9, 6],
endCol = [35, 37],
offset = [37, 39];
if (ind === -1 || e.range.columnStart < startCol[ind] || e.range.columnStart > endCol[ind] ||
e.range.rowStart < 4 || e.range.columnStart < e.range.columnEnd) return;
e.range.offset(0, offset[ind] - e.range.columnStart)
.setValue(new Date());
}

I don't think you can have 2 onEdits in google scripts.
If you comment out the f function, does the e one work?
cant you put them in one onedit function as a solution.
function onEdit(e) {
if (e.source.getActiveSheet().getName() !== "RS3 Points" ||
e.range.columnStart < 9 || e.range.columnStart > 35 ||
e.range.rowStart < 4 || e.range
.columnStart < e.range.columnEnd) return;
e.range.offset(0, 37 - e.range.columnStart).setValue(new Date());
if (e.source.getActiveSheet().getName() !== "OS Points" ||
e.range.columnStart < 6 || e.range.columnStart > 37 ||
e.range.rowStart < 4 || e.range
.columnStart < e.range.columnEnd) return;
e.range.offset(0, 39 - e.range.columnStart).setValue(new Date());
}
Something like that, but its untested.
I think If i'm reading your code correctly, you're looking for Not equals to sheet name, it might be better to change it to equals instead.
