Formula To Aggregate Totals for Year - google-sheets

Question

I have a spreadsheet that I use to keep track of climbing progress (snippet shown below). I have formulas and graphs that keep track of counts of specific grades over time, but I am having trouble with a formula to keep a running total (by year) of feet climbed. I intent to put this in another sheet.
Basically I would like a single cell that does something like ... if Sheet1!A:A begins with "21." and if Sheet1!E:E,"<>*%" (which means I actually completed the climb) then add the rows total climb length (Sheet1!J:J * Sheet1!I:I) to the running total for that year.
What is the best way to do this?

Answer 1

You can try using Apps Script and creating a script in order to manage your task.
So for example, you might want to take a look at the snippet below:
Code
function calculateTotal() {
let ss = SpreadsheetApp.getActive().getSheetByName('Sheet1');
let date = ss.getRange('A2:A').getDisplayValues();
let tries = ss.getRange('E2:E').getDisplayValues();
let lengths = ss.getRange('I2:I').getDisplayValues();
let total = 0;
for (let i =0; i<date.length; i++) {
if (date[i][0].toString().startsWith('21') != false && tries[i][0].toString().includes('%') == false) {
total = total+lengths[i][0];
}
}
ss.getRange('M2').setValue(total);
}
Explanation
The script above gathers all the values from the Sheet1 and loops through them. If the conditions check (the date should start with 21 and the E column does not contain %) then the corresponding length is added to the total; the total is then saved in the M2 cell in this case.
Further improvement
The advantage of using a script is that it is versatile and easier to manage. In this situation, you can make use of Apps Script's time-driven triggers; so assuming you plan on updating your spreadsheet every day at a specific time, you can create a trigger which will run right after it.
For example, the below function creates a trigger for the function above which will run every day at ~9.
function createTrigger() {
ScriptApp.newTrigger("calculateTotal")
.timeBased()
.atHour(9)
.everyDays(1)
.create();
}

Thanks Ale13 ... using your example and adding a couple of things (also needed to parseInt totals) ...
function calculateTotal() {
let ss = SpreadsheetApp.getActive().getSheetByName('Sheet1');
let s7 = SpreadsheetApp.getActive().getSheetByName('Sheet7');
let date = ss.getRange('A2:A').getDisplayValues();
let type = ss.getRange('F2:F').getDisplayValues();
let tries = ss.getRange('E2:E').getDisplayValues();
let lengths = ss.getRange('I2:I').getDisplayValues();
let laps = ss.getRange('J2:J').getDisplayValues();
let btotal = 0;
let rtotal = 0;
for (let i =0; i<date.length; i++) {
if (date[i][0].toString().startsWith('21') != false && tries[i][0].toString().includes('%') == false) {
// Totals for Bouldering
if (type[i][0] == "B") {
btotal = btotal + parseInt(lengths[i][0]*laps[i][0]);
}
// Totals for Top Rope or Sport
else {
rtotal = rtotal + parseInt(lengths[i][0]*laps[i][0])
}
}
}
console.log("Roped total = " + rtotal)
console.log("Bouldering total = " + btotal)
s7.getRange('B2').setValue(rtotal);
s7.getRange('B3').setValue(btotal);
}
