Hi nick_warren and lacrews,
For the record, no one at method ever gives up on a client and their forum questions....but the sad fact of the matter is sometimes we have other things to do that delay when we reply to a forum post.
I am currently working on trying to reproduce this issue you are reporting.
In the meantime, Nick_warren can you confirm following:
1. The method RecordID of the customer you are querying is correct (The fastest way is just to pull all customers and verify the recordid is correct)
2. Do you have multiple records in the customer table for this customer?
3. On the Customer and contacts list....what is the balance in the grid for this customer?
4. On the Edit Customer page...what is the value of current balance?
