Newbie select statement questions 'WHERE'

NEWBIE! I have some GET data coming from a previous search form.

How do I add the WHERE part ?

orig:

$query_get1 = "SELECT p_First, p_id, p_Last, p_Lvl, p_Sel
FROM contacts";

------W / WHERE...???

$query_get1 = "SELECT p_First, p_id, p_Last, p_Lvl, p_Sel
FROM contacts
WHERE p_First like $_GET['p_First'] or p_Last like $_GET['p_Last']";


I tried various things that make errors:
 
where p_First like '%$_GET['p_First ']%'";
where p_First like ".$_GET['p_First ']."";
Etc...

How can I make this work?
