Returning Resource URL from Resuorce Number

Hi, I'm quite new to modx Revolution so hopefully someone can help me with a little problem I'm having...

I've created a TV for a specific template, which has an input type of 'resource list'. The output type is text, and outputs the resource number. The problem i'm having, is turning that resource number into the resource URL.

E.g. I choose the resource 'about' (the about us page), and it returns the resource number '4' into my code. Currently my code looks like this...

<a href="myTV"> which returns <a href="4">

Obviously, the destination is not '4', and this needs to be the actual URL of resource 4.

Any idea how can achieve this?

Many, many thanks in advance for you help

Nest the TV tag as the value for the "make URL" tag.

Thank you very much!
