Javascript button not triggering

Hi ALL,

I craeted a button on the command bar and put a javascript file beneath it, to trigger when the button is clicked. The code is below;

var submitReceipt = function (executionObj) {
			
            var formContext = executionObj.getFormContext();
			formContext.getAttribute("ntt_submittofinance").setValue(1);
			formContext.data.entity.save();
			formContext.data.refresh();
		};

I just want to set a value and then save the record. Nothing works at when the button is clicked. Please someone with experience should. Thanks in advance for the help.
