listbox does not update with new records added to table in access

Question

I have a listbox on my search form that lets me search the table Patients using text criteria for firstname , lastname , ID and othernames . the SQL for the search Query:

SELECT 
    Patients.[Patient ID], 
    Patients.[First Name], 
    Patients.[Last Name], 
    Patients.[Other Names], 
    Patients.Gender
FROM Patients
WHERE (((Patients.[Patient ID]) Like "*" & [Forms]![SearchTab]![txtI] & "*") 
     AND ((Patients.[Last Name]) Like "*" & [Forms]![SearchTab]![txtL] & "*") 
     AND ((Patients.[Other Names]) Like "*" & [Forms]![SearchTab]![txtO] & "*") 
     AND ((Patients.[First Name]) Like "*" & [Forms]![SearchTab]![txtF] & "*"))
ORDER BY 
    Patients.[Last Name], 
    Patients.[First Name];

Search works fine but there is another form for data entry into the Patients table and none of the new entries are being found by the search form, but I can see them in the table.
Anyone can shed some light on the problem?

Answer 1

Try replacing this: [Forms]![SearchTab]![txtI]

With this: Nz([Forms]![SearchTab]![txtI])

For all 4 of your text search boxes.
