Problem with SELECT WHERE IN

Question

I'm having a problem with a SELECT clause...
the variables...
<cfset MyString=#getProducts.matches_with#>
<cfset myArrayList = ListToArray(MyString)>
the query...
SELECT *
FROM pricelist
WHERE supplier_code IN ('#myArrayList[1]#' , '#myArrayList[2]#')
The problem is, the select clause is only ever retrieving one row, despite their being several matches
The clause works fine when I change the WHERE line to
WHERE supplier_code IN ('E1775' , 'R1771')
What am I doing wrong here ?

Just wanted to say thanks all for the advice - I'm back on track now.
As you know I had a field 'matches_with' in the merchandise table which contains a comma separated list, which I now accept is bad design.
I wrote the following code to take each field and put it into a new table called matches_with, which contains two fields
product_code , matches_with_product_code. All done.
<cfloop query="getData">
    <!--- create an array based on the csv list of items in matches_with field --->
    <cfset myArray = ListToArray(#getData.matches_with#)>
     <!--- skip if no items in array --->   
    <cfif #ArrayLen(myArray)# gt 0>
        <!--- loop through item in the array --->
        <cfloop from="1" to="#ArrayLen(myArray)#" index="i">
            <cfquery name="insert" datasource="foo">
                <!--- insert each array item into SQL table --->
                INSERT INTO 00_matches_with (product_code, matches_with_product_code)
                VALUES ('#getData.product_code#' , '#myArray[i]#')
            </cfquery>
        </cfloop>
    </cfif>
</cfloop>
