If you set EJEJC_PLAYNICE=true;, then any jQuery statements under function EJEJC_shown() {} must be changed to ejejc_jQuery like so:
function EJEJC_config() {
EJEJC_PLAYNICE=true;
EJEJC_INITCSS = false;
EJEJC_POSTCALL=true;
}
function EJEJC_shown() {
ejejc_jQuery("#dscnt_cd").attr("innerHTML", "Athlete Code");
}
I'm seeing the shipping cost appear when I enter my ZIP code in your cart, so apparently you've already resolved that matter by now.
