JOIN statement

I need some help.. I have two separate database tables.  What I need to do is display the data from one if a variable exists in another.  Heres my statement that pulls the correct data from one.  But how do I attach the other so it's only pulling the data from the tables if the ID number is a certain one. 

	$strQuery				= "SELECT intID, strTypeName FROM tblTypes WHERE boolActive = 1 ORDER BY intSortOrder ASC, strTypeName ASC";
	$queryGetTypes			= db_query($strQuery);

The table I need to join has the following fields: intID, intTypeID, intCategoryID

I need to pull the data for the intCategoryID=1 for example. 

Please help!

Google helps you.

Thanks... So I think i'm pretty close, i'v seemed to make the join statement, just need a little help on completing this full statement. I got this but it's pulling the first field and repeating it instead of listing all the ones with that ID

<?php
// Make a MySQL Connection
// Construct our join query
$query = "SELECT 
    * 
FROM 
     tblTypes
JOIN 
    tblTypeToCategory 
ON 
   strTypeName=intCategoryID WHERE intCategoryID = 1 ORDER BY intSortOrder ASC, strTypeName ASC";

$result = mysql_query($query) or die(mysql_error());


// Print out the contents of each row into a table 
while($row = mysql_fetch_array($result)){
echo $row['strTypeName']. " - ". $row['intCategoryID'];
echo "<br />";
}
?>

Can you post your database structure? Does strTypeName really join to intCategoryID? 

Well now that i'm looking at this might need to join 3 to get these results.  Here is the structure

tblTypes

intID  strTypeName

tblTypeToCategory

intID  intTypeID  intCategoryID

tblCategories

intID  strCategoryName 

Ideally what I need is tblTypes to pull all the names that are associated with tblCategories specific ID

So for example. 

tblTypes has Item 1, Item 2, Item 3

tblTypeToCategory has the category ID's and Type ID

tblCategories has the main ID that we are looking to pull so the TypeToCategory is basically the bridge between the two
