AbleCommerce Shopping Cart Software

If I copy the Basket.ascx file into the Conlib Custom folder and change
the scriptlet to:
[[ConLib:Custom/Basket]]

I get this error on the page:

[[ConLib:Custom/Basket]] The file '/DCPAC7/ConLib/Checkout/Google/GoogleCheckoutButton.ascx' does not exist.

I changed:
<%@ Register Src="../Checkout/Google/GoogleCheckoutButton.ascx"
To:
<%@ Register Src="../../Checkout/Google/GoogleCheckoutButton.ascx"
and it works now.
