Shortcode in a template didnt work

Hi there, I really like this plugin and wanna use it. But I have a problem…
I needed to put the shortcode in one of my page’s template.
So to try it first, I have created the long shortcode after setting up the upload field as I want. And I have put the shortcode into a normal page just to try it. It worked perfectly fine. BUT… when I place the same shortcode in a php template like this example:
<?php echo do_shortcode( ‘[my-long-shortcode-generated-by-wp-file-upload]’ ); ?>)
It shows up the field fine, but you cannot upload any file as when you click on select file button, it is not opening the selection window, and nothing is going on…

I know you must be a busy person. But I was wondering if there’s any chance you could help me to solve this ? Many thanks in advance 🙂
