Product Relations List Box box help....

[David]

Hi,

I have a field which holds the Product IDs of related products in a
format of:

1#5#4#7

Where the numbers are the Related Product IDs.

I am trying to create a form to manage this info.

I thought just have two list boxes. One with all the product names and
the other with all the related products. An add & remove between them.

I understand how I could add products by just adding #number when any
product is added.
How do I remove a product from the list box whilst also removing the
correct #number or number (if it was the first) from the data field

Appreciate your halp

You are actually storing multiple values in one field? That's a cardinal sin
in normalization.

Repent, and change your table design so you have a related table to hold
these values as multiple *records*. The one-to-many relation will set you
free from your immediate problem, and give you the chance to do dozens of
things you cannot currently do without writing ridiculous parsing routines.
