Hello,

I am selling photo prints and I have set prices for certain unmounted sizes

Print Size 16"x24" (2') Unmounted + 295.0000
Print Size 24"x36" (3') Unmounted + 750.0000
Print Size 32"x48" (4') Unmounted + 1250.0000
Print Size 40"x60" (5') Unmounted + 1950.0000
Print Size 48"x72" (6') Unmounted + 2950.0000
Print Size 48"x96" (8') Unmounted + 3950.0000
Print Size 24"x96" (8') Unmounted + 2950.0000

What I am wanting to do is to have a attribute check box that can only be selected if they pick a size above that offers mounting, i.e.

Add mounting x

But depending on the size of the print the mounting price is different i.e.

Print Size 16"x24" (2') Unmounted + 295.0000 +80
Print Size 24"x36" (3') Unmounted + 750.0000 +200
Print Size 32"x48" (4') Unmounted + 1250.0000 +400
Print Size 40"x60" (5') Unmounted + 1950.0000 etc.
Print Size 48"x72" (6') Unmounted + 2950.0000
Print Size 48"x96" (8') Unmounted + 3950.0000
Print Size 24"x96" (8') Unmounted + 2950.0000

Is there a way to do this?
