Filemaker relationship wont relate

[4.Pack]

Help I have a database for correspondence that gets the company details from one DB, and the Person details from another DB. Using a series of scripts to concantenate the various record id's and pull into the correspondece DB, then break up the record numbers again to use for the relationships this all works fine.

The relationships are all defined correctly, yet the relationship that filemaker gets for the person details is totally incorrect!!!

to give you an idea,

this is the concantenated unique ID no's and they are unique as I checked them:

306200110261512641537IB 64200117521212599582S

on the left is the person contact no

on the right the company id no

thus this splits into

306200110261512641537IB

and

64200117521212599582S

these are the numbers(fields) that are then used to define the relationship.

al ok so far, except that now if I ask filemaker to show me the unique id number for the person using the relationship it gets me this

306200110261512641530IB

the last number digit should be 7 ? not 0 it seems as if filemaker is taking the first almost the same number it comes accoss and not the propper number

the other relationship seems to work fine however

what the hell is going on !!!!!

figured it out, filemaker only indexs 20 chars, and the unique numbers are like 23 chars long.
