I got the relation to add up all the component lengths based on your reply David but I cannot get it to populate in the table I have. I have the parameter "overall_length_1" and it has a value of "120" and I am using "&asm.mbr."user defined"" and for user defined i typed "overall_length_1" to no avail.
Ideas?
