I have tried adding the sellers number to the listings details sidebar tpl file using the code.

Code:
Only registered members can view the code.
But it keeps returning the number like this a:031|n:131313 where it should be (031) 1313133.

I also want to hide like putting xxxxxxx over last 7 digits until someone clicks on the number then it will be shown. Like the immage attache.
