Test runs fine by itself but fails when executed in runner.cfm

Given this code. If I run it individually either by executing the class itself or clicking on this class in the runner.cfm UI. It works but when I execute all of the test in the runner it fails with the FORM.cost being 0 rather than 1.

describe( "profit_calculator.cfm", function(){
            // before each spec in THIS suite group
                FORM.cost   = 1;
                savecontent variable='result' { include '/profit_calculator.cfm'; };
            // after each spec in THIS suite group

            it("should render' ", function(){
               expect( result ).notToBe( '', 'result is empty' );
