[ic] Modifying posted form with mv_click

[Jamie Neil]

Sorry - got it now (amazing what 2 hours sleep can do for you)

Just for the record, I did it like this:

                                [button
                                        text="Remove Item [item-increment]"
                                        src="remove.gif"
                                        hidetext=1
                                        form=basket
                                ]
                                mv_todo=refresh
                                mv_nextpage=ord/basket
                                [quantity-name]=0
                                [/button]

The key is to use [item-increment] in the button text so each button has a
unique name.
