'order_total/ot_lev_discount.php'); $ot_lev_discount = new ot_lev_discount(); echo $ot_lev_discount-&gt;od_amount; </code></pre> <p>I seem to be able to call the classes global variables in this way but not the ones in the classes function. </p>

    1. COWhat's in the constructor? And what does `$ot_lev_discount->od_amount` return? Is `$od_amount` a property of `ot_lev_discount`? It would help if you posted more (all) of the class.

    2. COVariables in a class method are scoped to that method, so not accessible outside; in exactly the same way that local varaibles in a normal function are scoped to that function.... why did you think otherwise?

    3. COI added the entire class to look at. $ot_lev_discount->od_amount isn't returning anything. At least not when I echo it like I am? I'm not sure what you mean by is it a property of ot_lev_discount

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
