Javascript Simple If Else innerHTML == 'something' not working

I have a seemingly simple javascript function I am trying to create that checks the value of an elements innerHTML and spits out a value based on the answer, but for the life of me I can't get it to work and don't get any errors. This function is triggered by onclick events and doesn't need to have window.onload added. Any insight anyone could give me would be much appreciated!

function updateShippingCost(country_region) {
    var url;

    var kkdk = '';
    var planTitleesd = document.getElementById('planTitle').innerHTML;
    console.log(planTitleesd);
    if (planTitleesd == '10 Day Supply // 20 Capsules // FMF') {
        kkdk = '5.99';
        console.log(kkdk);
    } else if (planTitleesd == '20 Day Supply // 40 Capsules // FMF') {
        kkdk = '9.99';
        console.log(kkdk);
    } else if (planTitleesd == '30 Day Supply // 60 Capsules // FMF') {
        kkdk = '14.99';
        console.log(kkdk);
    }
}

Oddly, console.log(planTitleesd) returns a value, but all the others do not. Thanks for your help!
