    concatenating data into one text field

    Hello,



    I am making a database for maintaining an inventory of our hazardous waste bottles. The "containers" table has 10 text fields for the user to enter each ingredient, let's call these fields [Name1], [Name2], etc, in the bottle into, and a corresponding field to enter the concentration, lets call those [Conc1], [Conc2], etc. This concentration is a percentage, but they do not enter the % symbol. Some bottles will have all 10 of these filled out, some will only have 1. It depends on what is in the container.

    I have a report that shows the "inventory" of everything in a room - each bottle, including the contents of the bottles.

    On that report, I'm trying to list the contents in the following format:

    [Name1] [Conc1]%, [Name2] [Conc2]%, [Name3] [Conc3]%, . . . [Name10] [Conc10] %

    A simple concatenation, if there are only 2 ingredients, will show:
    Ethanol 20%, Water 80%, %, %, %, %, %, %, %, %

    For now, that is what I'm doing, but obviously what I want it to do is say:
    Ethanol 20%, Water 80%

    Could someone please help me with this? I've been trying to figure it out for several days now, I'm just lost.

    Welcome to the forum !

    Unfortunately you have "Spreadsheeted" you table design, you should have a table that is formatted more like


    ContentsId(AutoNumber PK), WasteBottleID_FK, ConcName, ConcPerc


    Then your query/report outout would be simple to achieve, and if ingredient 11 arrived one day or ingredient 23 it wouldn't matter, as this design of table can accommodate a totally variable number of ingredients.

    you do not seem to be using the data correctly. The Bottles inventory should not have 10 fields each.
    instead , it should only have 2 in a subtable then you can have infinite bottles, not just 10 AND follow relational db rules.

    tblBottles:
    ParentID, BottleID, Name, Conc
    1,1,Ethanol, 20
    1,2,Water, 80
    1,3,glycol, 1

    But to answer your question:
    [Name1] & " " & [Conc1] & "%" & & " " & [Name2] & " " & [Conc2] & "%" & ….

    Agree with tall the suggestions for a proper database design.

    To add to ranman's suggestion for your current setup I would use something like this to avoid the "%" showing for the empty fields:
    ([Name1] + " " + [Conc1] + "%") & (", " + [Name2] + " " + [Conc2] + "%") & (", " + [Name3] + " " + [Conc3] + "%") &......

    Cheers,
