Limit Combobox to only 1 instance in the records
Experts,
I have this form with cboBankType.
The form is Continous Forms with underlying table : tblBanks_Participating
ID = BankEnterID
I want to limit a users input on this cboBankType to only 1 occurence of a "Initial Issuing Bank" (the ID is =1 on this BankType)...meaning that there can only be 1 "Initial Issuing Bank".
When creating records, How can I limit a duplicate entry on cboBankType for only when the cboBankType ID is =1 which corresponds to "Initial Issuing Bank"? (this means that the previous record has this banktype description already)...
cboBankType [BankType field name] has this as a row source:
SELECT tblBankType_dropbox.BankTy
Please ask if you have questions. I am thinking that possibly there is some type of Validation rule you can setup or something pretty simple to limit to only one "Iniital Issuing Bank".

Mbizup: will try that....
Peter:
<But first can you say what happens after the '1' - can all other values in the combo appear more than once, or are they also limited to a single occurrence.
Short answer: yes...others are not limited...as many as want.

I think I will try a different approach and see how that goes. thank you for the information.
If DCount ("*", "YourTable", "BankTypeID = " & 1) > 0 then
me.cboBankType.Rowsource = "SELECT tblBankType_dropbox.BankTy
End IF
