conditional based attributes to calc shipping?

Is it possible to have conditionals for calculating shipping costs?

I only have one product (a photographic print) but that product has options...

Size (16"x24", 20"x30", etc)
Paper (the type of paper used)
Mounting

Past a certain size shipping a mounted print flat (vs. rolled) becomes prohibitively expensive so I want something along the lines of:

if( (shipping_size >= 30x40) & (mount == true) )
{
shipping_price += $30.00;
}

If that didn't make sense...

If the shipping size is greater than or equal to 30"x40" and the client wants the print mounted then add $30 to the shipping cost.

Is this possible?

I do not believe that shipping_size is a table or record in a table

I haven't looked but check your attribute table structure for a possible

I doubt it is.... I'm an ex c/c++ software engineer. Web stuff... don't touch it. :-) I was just thinking out loud in terms of the logic I wanted. (so ignore the variables... they have no bearing on the actual code in Zen Cart... I'm just describing the behavior I'd like to see).

Then yes you are on the correct track
