I need some help please

[dcrake]

What you should be doing is this

User selects something from combo 1

Set the rowsource for combos 2,3 & 4 to ""
set the rowsource for combo 2 to cascade from 1



User selects something from combo 2

Set the rowsource for combos 3 & 4 to ""
set the rowsource for combo 3 to cascade from 2

User selects something from combo 3

Set the rowsource for combo 4 to ""
set the rowsource for combo 4 to cascade from 3


What you should not be doing is

Letting a user select from a combo box unless the preceeding combo has a value in it.

Step though each stage to validate your coding.

Ok i fixed that.Now i can choose from a combo box only if i have made a selection from the previous one.The problem is i still get the same message for the last combo box.
=================================
Private Sub Combo7_AfterUpdate()

strFile = Me.Combo7.Column(3)

End Sub
=================================

Run-time error '94' :

Invalid use of Null

Could i have made a mistake that i cannot see?I have checked and rechecked the code and it is exactly the same as the first form i had created with your help(minus the cascading combo boxes).

[dcrake]

Ok try this

 
Private Sub Combo7_AfterUpdate()
Dim x as integer
For x = 0 to Me.Combo7.Columns.Count - 1
   debug.print Nz(me.combo7.Column(x),"Blank")
Next

strFile = Nz(Me.Combo7.Column(3),"Nothing in Column 3")
msgbox strfile
exit sub
 
 


End Sub

Wnat happens now?

I am so so stupid.I was so sure my code was correct that i checked it word by word and i found what was wrong.When i chose from the third combo box it was only loading the 3 of the 4 columns of the table.I remember fixing this but it seems i didnt save the form after that.Now it works.Thank you!!!

Now one final problem i have to solve and im done after that.I have created a table with 5 columns (name,telephone,cellphone,fax,information).I have a form with 1 combo box and a list.How can i do it so when i select a letter from the combo box (a,b,c,d,...,z) i get the names that start with that letter in the list.What i want to do as you probably think is a phone catalogue with names.Can it be done so the names appear in alphabetic order?

[dcrake]

Can you not use the auto complete in the combo box to fill in the rest of the name? Or do you want to use an auto find list box?

By that I mean you have a textbox that you type into and as you type in it filters the list box with names that begin/contain the phrase you are typing in?

No i just want to select a letter from the combo box and the list to show me all the names for that letter.

[dcrake]

Then look at the properties for the combo and it will have one that says Auto Expand set this to yes.

And how will the list be updated with only the names that start with the letter i chose from the combo box?
