Javascript Problem

[Shadow121]

I"m trying to make a refresh captcha thing but it doens't seem to be working.

function refreshCaptcha()
        {
            var imgPath = serverDomain + "verificationimage.png";
            var img = document.getElementById('captcha');
            img.src = imgPath;
            var inputField = document.getElementById('captchaInput');
            if(inputField != null && inputField.value != '')
            {
                inputField.value = '';
                inputField.focus();
            }
        }

It will change the src attribute, but the image will not regenerate.

Yes, serverDomain variable is declared.
