custom field

In old vbulletin when we create custom multiple lines field and add some links in custom field they are shown like plain text...i was wandering how is that solved in this software-can we add links in custom field?

And can someone tell me how can add links and make it clickable in old vbulletin 3.8.x? How to add comma between two links?

I tried code like this <a href="$post[fieldX]">$post[fieldX]</a> and it works but if i enter two links they are linked to separate them and make each one clickable?
