Simple if, then problem (1 Viewer)

[colinmunnelly]

I am trying to do a nvery simple if, then statement but it doesn't seem to be working as it should. I know the solution must be really simple. Anyone shine some light.

Private Sub Form_AfterUpdate()
If text69 = "" Then
MsgBox ("no impact")
Else
'DoCmd.OpenForm "notice_input_form", acNormal
End If
End Sub

You have two problem in your code
First:

MsgBox ("no impact")

Should be:

MsgBox "no impact"

if you don't want to handle the return value of MsgBox

Second:

If text69 = "" Then

text69 doesn't refer to a field on your form like that
It should be something like this:

If me.text69 = "" Then

So everything should look like this:

Private Sub Form_AfterUpdate()
If me.text69 = "" Then
    MsgBox "no impact"
Else
    'DoCmd.OpenForm "notice_input_form", acNormal
End If
End Sub

Thanks for your reply. Still a problem though. If text69 is null the message box still does not appear. It opens the form "notice_input_form"

You could change it for:

If (trim(me.text69) = "") or isNull(me.text69) Then

This way, your message box will appear if the textbox contain nothing of is fill with blank.

thanks works well. Any idea why the original didn't work.

If your talking about my original code, it wasn't always working because I was comparing text69 with "" and a Null value isn't equal to "" even if it looks the same in the field.

You should always use the function IsNull to check for a Null in a field and Trim() to check if your field is fill only with blank.

Hope I'm clear enough.
