I have a database and am trying to figure out a way to automatically figure the shipping rate of packages sent via FedEx. I have a table called FedEx rates which includes fields for Wt, zone 1 zone 2, etc. I have another table (LineItems) that figures the wt. of the package and I have another table (Zip Code) that figures the shipping zone. Is there a way that I can pull the rate from the FedEx Rate table to get the shipping cost of the package? I am using Filemaker 12 Advanced.
