Try this:

Put a new worksheet in your workbook, then:
A1: MfgID
B1: MfgName
A2: 0123 (or whatever products you have)
Note: If you want leading zeros...Format these cells as Text
FormatCellsNumber TabCategory: Text

B2: Fred Bloggs Ltd
Continue filling in the list

When done...
Select from A2 through the last item in Col_B
InsertNameDefine
Name in workbook: LU_MfgInfo
Refers to: (your already selected list)
Click the [OK] button

Then, on your input sheet...for a MfgID are in A2...
B2: =IF(ISBLANK(A2),"",VLOOKUP(A2,LU_MfgInfo,2,0))

Does that help?

I am creating a database. Every time I enter a certain number (e.g. my
manufacturer's code) I'd like to be able to make the (manufacturer's) name
appear in a nominated cell. E.g every time I enter 0123 in one cell, Fred
Bloggs Ltd appears in an adjacent cell.
Can excel do this. I haven't a clue about Macros! Thanks1
