Passing arguments to Pages

Hi,

I have several forms which have an display/edit/delete approach to data 
e.g.

Display shows
-------------------
Order  description   cost  operation
1         my order 1   $10   Edit    Delete
2         my order 2   $20   Edit    Delete

Delete shows
------------------
Order ......  1
Description ...... my order 1

Delete YES/NO


When you click Edit is goes to a new form by passing an array

With forms this works fine and well.

I wanted to now pretty it all up by using blocks/panels and pages.

I have managed to create the pages using bibble_dep_block_info and 
bibble_dep_block_view. I have placed these their own pages and they 
appear under pages. However I cannot find a way to pass the arguments to 
the pages and subsequently to the blocks.

I am using D7.

On forms you can pass mymodule_form/%my_array but I cannot see how to do 
this with blocks.

thanks all
Iain
