Search form multiple multi select list box's Error

15 New Member
Hi Everyone. Thanks for your time.

I am trying to create a search form that will allow users to select criteria from multiple multi select boxes. So far i have managed to achieve a search option for 2 list boxes:- county and nationality, while trying to add a third multi select list box for qualifications search is where i encounter my problem.

I've copied the working code from my working list boxes, however it cant seem to pick up the search value from the qualification list box.

I think this error may stem from the relationships but i am not sure.

This is the record source property of one of my working list boxes:

lstNationality :SELECT [tblNationality].[NationalityCode], [tblNationality].[Nationality] FROM tblNationality;

This is the record source property of my new troublesom qualification list box:

SELECT [tblQualificatio ns].[QualCode], [tblQualificatio ns].[ShortQual] FROM tblQualificatio ns ORDER BY [ShortQual];

Am i correct in asuming that it's a relationship issue?

I have attached a screnshot of my relationships, and included a copy of my code in this post, if any body has any ideas they would be greatly appericated.
Many thanks once again for your time Kind regards, JAMES

  1. Could it be as smple as a Syntax Error, I am referring to Code Line #98
    Expand|Select|Wrap|Line Numbers
    1. 'Check for qualCode in multiselect list
    2. For Each varItem In Me.lstqual1.ItemsSelected
    3.   qualCode = qualCode & " [tblqualifications].[qualCode] = """ & _
    4.              Me.lstqual1.ItemData(varItem) & """ OR "
    5. Next
  2. You are treating the [qualCode] Field as if it were a String, is this Field, in fact, a String?

Thanks for the reply hugely appreciated.

I have tried your suggestion and its giving me a runtime error
"data type mismatch in criteria expression"

If i try [tblqualificatio ns]_[qualCode] i get a syntax error in query expression
'( [tblqualificatio ns]_[qualCode] = "3") this error seems somewhat correct because its recognising the qualCode from the listbox.

In answer to your question i am confident that its a string because the two working search options county and nationality seem to work following this principle.

Its strange because my code works for county search with
[tblMemberDetail s_CountyCode] where as my code for nationality search has to be [tblNationality. nationalityCode].

I dont know why this is but i am assuming that this might be giving me issues with qualification searching via the multi select list box.

having reviewed my database i discovered that the fields for my successful searches are stored in tblMemberDetail s where as the field for qualification is located in another table. i think i need to reference tblMemberQualif ications.qualCo de as opposed to tblQualificatio ns.qualCode but yet again i am not sure.

I have attached a sample version of my database, if anybody could have a look at it i would greatly appericate it as this is driving Me CRAZY.

Thanks again for all the support.

Regards James.

Right now, I'm on vacation and working with an older Version of Access (2000), which is essentially useless in this case. When I return home on Friday, and if this Thread has not yet been resolved, I'll have a good look at it and get back to you during the weekend.

If line 12 were Debug.Print Me.sbfrmSearchR esults1.Form.Re cordSource, you would have the actual SQL string used. If you paste that into the SQL window in query design, then switch to DataSheet view, what happens? Switching to Design view and looking at the grid, are there any obvious errors? Does removing some of the criteria get the results it should? This is one quick way to narrow the problem down, and you should quickly find the error.

If not, using the Design Query, design a new query which exactly mimics your problem. Enter the criteria that you are using in the various controls on your form. Switch to DataSheet view to be sure you got it right. Switch to SQL view and compare the generated SQL statement to the Debug.Print you inserted in line 12.

thanks for the responce.

I figured is out it was finally with some advice from my friend.

qualCode a numeric value in the table (the data type) so, i don't want quotes around the value.

Thanks so much for all the assistance.

All the best and thanks again.
