In the item I need to call a javascript so I have this line:
Any chance I can change ht tp://www.somesite.com.mk/ with something and to work?

Hello,

I am not sure I understand the issue.
Can you elaborate?

More code would definitely be useful from above and below the script tags.
Take a look at your item.php file and search for the script tag and look how it is used there and where the js file is stored
Usually the text tag is first and the src is last and the file is located in a dir on the server where other js files are kept
Before using the script tag you must close php if open and reopen the php tag after the /script tag
