Hi there, i am facing a real problem, I created 2 tables.

MovieCategory(MovieCategoryID, CategoryName)
Movies(MovieID, MovieCategoryID, Title, ratings ...)

I have populated the MovieCategory tables with some data, and i want to test out my Movie form that i have created.

In my Movie form as attached in the screenshot, i have to fill in all the relevant movie details, however, i populated a dropdownlist from the MovieCategory table showing the Categoryname.

The problem that i face now is i want to enter the Movie datas into the movie table, but my dropdownlist is populated with the CategoryName, i need to change it to its repective MovieCategoryId but i am unable to do this. I have tried lots of methods but i still can't figure out how to solve this. Will really need some help here.

The code attached below is something that i have tried, but to no avail. Can anyone please advice me on how to go about it?
Private Sub ddlCategoryName_Change()
    
       Dim strOne As String
       strCatName = Me.ddlCategoryName.SelText
       
       Dim strSql As String
       strSql = "SELECT MovieCategoryId FROM MovieCategory WHERE CategoryName =" + strCatName
       
       Me.ddlMovieCategoryId.RowSource = strSql
       Me.ddlMovieCategoryId.Requery
       
End Sub

I'm confused why you have a dropdown for both CategoryName and CategoryID:  they both represent the same column in movie table.

Nevertheless, let me proceed with an answer for the CategoryName cbo.
1.  Make MovieCategoryID the control source for that Cbo  (then it will be bound)
2.  Make Rowsource = "Select MovieCateoryID, CategoryName from MovieCategory"
3. Make Number of Columns = 2
4. Make Column Widths = 0;    (this hides the ID column)
5. Make Bound Column = 1

OK, I see reason for two CBO's now:  one for selecting records; one for viewing/updating records.

Generally, the selection CBO would go at the top--perhaps even in the form header. But, you can leave it at the bottom if you like.  Also, it seems to me that you should select by Movie, not by MovieCategory--am I missing something?

Anyway, for the view/update CBO follow the directions I gave above.

For the selection CBO, the steps are the same except for step 1. Do NOT assign a control source--leave it unbound.  In step 2, you can make the rowsource from the Movie table or the MoveCategory table--I'm confused what you want in that regard.
