Help calculating totals

Hi Folks. I have a statistics page showing how many centers I have trained and the total trainings for all centers together. Now I need to get the individual center totals. Each center that had training is listed once. I need the individual totals to go in the red circle in the pic. I’m working with 2 datasets. One with the centers (#centerData / centers ) and one with the trainings (#dynamicDataset / training_progrss ). I’ve put my code below for the entire page. Any help with this is greatly appriciated.

import { local } from ‘wix-storage’ ;
import wixData from ‘wix-data’ ;
import wixWindow from ‘wix-window’ ;
import wixLocation from ‘wix-location’ ;
import wixUsers from ‘wix-users’ ;

let fadeOptions = {
“duration” : 0 ,
“delay” : 3000
};

export function dynamicDataset_ready() {
$w( “#dynamicDataset” ).setFilter(wixData.filter()
.contains( “trainer” , ‘XXXX’ )

    ) 
    .then(() => { 
        console.log( "Dataset is now filtered" ); 
    }) 
    . **catch** ((err) => { 
        console.log(err); 
    }); 

}

export function filter_click(event, $w) {
$w( “#count” ).show();
$w( “#centers” ).show();
$w( “#centersRepeater” ).show();

wixData.query( 'training_progrss' ) 
    .contains( 'trainer' , $w( "#staff" ).value) 
    .lt( 'training_date' , $w( '#toDate' ).value) 
    .gt( 'training_date' , $w( '#fromDate' ).value) 
    .count() 
    .then((num) => { 
        $w( "#count" ).text =  ''  + num; 
    }); 

wixData.query( 'training_progrss' ) 
    .contains( 'trainer' , $w( "#staff" ).value) 
    .lt( 'training_date' , $w( '#toDate' ).value) 
    .gt( 'training_date' , $w( '#fromDate' ).value) 
    .distinct( 'center_id' ) 
    .then((num2) => { 
        $w( "#centers" ).text =  ''  + num2.totalCount; 
    }); 

wixData.query( 'training_progrss' ) 
    .include( 'center_id' ) 
    .contains( 'trainer' , $w( "#staff" ).value) 
    .lt( 'training_date' , $w( '#toDate' ).value) 
    .gt( 'training_date' , $w( '#fromDate' ).value) 
    .descending( 'training_date' ) 
    .find() 
    .then((results) => { 

let items = results.items;

        items = items.filter((e, i) => items.findIndex(q => q.center_id.title === e.center_id.title) === i); 
        $w( '#centersRepeater' ).data = items; 
        $w( "#centersRepeater" ).onItemReady(($item, itemData) => { 
            $item( "#center" ).text = itemData.center_id.title; 
            $item( "#url" ).text = itemData.center_id.subdomain; 
            $item( "#link" ).link = itemData.center_id.subdomain; 

// $item(“#centerTrainings”).text = ‘’ + itemData.center_id.title.totalCount; // this just shows the same number for all
console.log(itemData.center_id.title);
})
})

}

export function reset_click(event, $W) {
$w( “#dynamicDataset” ).setFilter(wixData.filter()
.contains( “trainer” , ‘XXXX’ ))
$w( “Staff” ).value = “Filter by Staff”
$w( “#centersRepeater” ).hide();
$w( “#count” ).text = ‘0’ ;
$w( “#centers” ).text = ‘0’ ;
$w( “#count” ).hide();
$w( “#centers” ).hide();
$w( “#fromDate” ).value = new Date();
$w( “#toDate” ).value = new Date();
}

Still looking for help if anyone can spare some time…
