Good day . I am a new user . I want to know if anybody could help me with the following problem . We manufacture spare parts . The current database we use provide me with bill of materials . But the catch is it cant support manufacturing in total . I started making a database with tables and querries . The problem i got is that you got a part number or stock item but the catch is each part number has dfferent parts used to make that one part . Now i got my tables and querrie but when i make a form to edit data for example part number 23ae uses 20 bolts , 20 nuts ,20 washers . I have a lookup column to lookup the number and a text box to put in how much i need of 23ae . In the lookup three 23ae's come up and when i edit it for instens i want 4 only the firts line gets the data but the other two stays blank . How can make a code to update all the 23ae quantity needed to 4 . Please help .
