I keep getting 404 errors when I type. 

localhost/shirt.php?id= followed by an number from an array I created

```
RewriteEngine On
RewriteRule ^shirts/$ /shirts/shirts.php
RewriteRule ^shirts/([0-9]+)/$ /shirts/shirt.php?id=$1
RewriteRule ^receipt.php$ /receipt/ [R=301]
RewriteRule ^contact.php$ /contact/ [R=301]
RewriteRule ^shirts.php$ /shirts/ [R=301]

RewriteCond %{QUERY_STRING} ^id=([0-9]+)$
RewriteRule ^shirt.php$ /shirt/%1/? [R=301]

```
