[ic] double entries in basket using text link

Hi people,

I have a strange problem regarding the basket and double entries 
appearing when I use a text link as opposed to the 'form' approach. I 
need to use a text link as I wish to pass an attribute with the order 
request as part of a [perl] block...

<snip>
$link = $Tag->page( { href => "ord/basket",
                       form => qq{
                                  mv_action=refresh
                                  mv_order_item=$sku
                                  item_attr=$item
                                  }
                    } ) . "BUY</A>";
</snip>

This works fine when you *first* arrive at the basket page as does 
the following which I used as a sanity check...

<snip>
[page href="ord/basket" form=|
                              mv_order_item=000059
                              mv_action=refresh
                              |]buy[/page]
</snip>

However when you either purchase another item, or just plain "go 
back" to the basket page there is an identical entry of the last 
ordered item using both the examples above -- I should point out that 
this is not the old "Reload/refresh" problem where you are submitting 
the form twice, this is occurring after leaving the basket page 
altogether.

Is this not possible to do (text link order), ergo I'm being a pratt again?
Any help, abuse or pointers most welcome.
Kind regards
Dave
