Lookup from Repeating Field

[hank_2003]

I have a Quotation file, Products file, Line Items file and a Customer file. The customer file has a Price Lookup filed to determine want price the quotation will lookup (10 prices in total). The Quotation layout has a portal showing Line Items. The file works fine except that I have a Calculation field (Unit Price CAL)working filed to look up the Product cost repeating field and displaying correctly. I want to be able to edit this field some times and this cannot be done because it is a calculation field. I have created another field in the line items (Unit Price LU) to lookup the Unit Price CAL field through a relationship Line Items 2. This is not working . Can anyone help?

Whats the calculation in the repeating field and what sort of "editing" do you want to be able to do?
