Refreshing calculation field when using JS/PHP

Hi everyone I’m running into some issues when combining both the built-in calculation functions in the form along with my own logic that utilizes different numbers in each field depending on dropdown choices that a user makes.

When the form is submitted, the number is reflected accurately and everything is correct, but while the user is filling out the form, my javascript numbers aren’t being reflected in gravity’s calculation.

So for my question: Is there anyway to refresh the calculation field?

I’ve tried moving the script into an html field so that it doesn’t just update on the server-side, but I’m still getting the same issue where my total amount doesn’t update on the client-side.

//add_filter('gform_calculation_result', 'gf_custom_script'); trying to override calculation of front-end 
function gf_custom_script(){ //this is for commission disbursement request REAL ESTATE
	<script type="text/javascript">
			jQuery('#input_6_5, #input_6_17, #input_6_178').change(function(){
				//input_6_5 is sale price 
                //input_6_17 is property type 
				var sale_price = jQuery('#input_6_5').val();
				var property_type = jQuery('#input_6_17').val();
				var insurance_fee = jQuery('#input_6_77').val(); //E&O Insurance/Risk Management Fee

				var regex = /\d+(?:\.\d+)?/g;
				var match;	
				var matchArray="";
				//var match = regex.exec(sale_price);
                //the exec method executes a search for a match in a specified string and returns a result array or null
				while (match = regex.exec(sale_price)) {
				//var formated_string = match.join('-');
				//pricing = formated_string.replace("-", ""); 
				var broker_commission = calculate_broker_commission(matchArray,property_type);
				var eo_insurance = calculate_eo_insurance(property_type);
				var smart_buy = calculate_smart_buy(smart_buy_combo);
				jQuery('#input_6_179').val(smart_buy); //for smart-buy calculation
				jQuery('#input_6_177').val("+$"+smart_buy); // for smart-buy front-end
				jQuery('#input_6_77').val(-eo_insurance); //for calculation
				jQuery('#input_6_175').val("-$"+eo_insurance); //separate field for visibility
				jQuery('#input_6_141').val("-$"+broker_commission); //this is also company dollar 
				jQuery('#input_6_24').val(-broker_commission); //this is company dollar (hidden) used for calculation
			function calculate_broker_commission(sale_price,property_type){
