shipment choices at checkout?

[pike15]

hmm, i feel like im running across a strange issue; have already spent a few hours trying to figure it out.  any help is greatly appreciated.

i want to offer two shipment choices within the three regions can/mex, europe, asia. so i set it up using the shipping calculator, but at checkout there is no opportunity for the customer to select between the two options; it automatically chooses the cheaper option.  how can i fix this?
