Hello Access experts,
I am just new in this field and struggling with my code. I have a nested IF and it works in query but not sure how to apply it in form. I am thinking of making an event expression under "After Update". The idea is to populate the Description field by concatenating other fields. Below is the code I did in query, all help is appreciated.
Description: IIf([Name 3] Is Not Null And [Width] Is Not Null,(Trim([Material] & " " & [Type] & " with " & [Name 1] & ", " & [Name 2] & " and " & [Name 3] & ". Approximately " & [Width] & "mm x " & [Height] & "mm.")),IIf ([Name 3] Is Not Null And [Width] Is Null,(Trim([Material] & " " & [Type] & " with " & [Name 1] & ", " & [Name 2] & " and " & [Name 3] & ".")),IIf([Name 2] Is Not Null And [Width] Is Not Null,(Trim([Material] & " " & [Type] & " with " & [Name 1] & " and " & [Name 2] & ". Approximately " & [Width] & "mm x " & [Height] & "mm.")),IIf ([Name 2] Is Not Null And [Width] Is Null,(Trim([Material] & " " & [Type] & " with " & [Name 1] & " and " & [Name 2] & ".")),IIf([Name 1] Is Not Null And [Width] Is Not Null,(Trim([Material] & " " & [Type] & " with " & [Name 1] & ". Approximately " & [Width] & "mm x " & [Height] & "mm.")),IIf ([Name 1] Is Not Null And [Width] Is Null,(Trim([Material] & " " & [Type] & " with " & [Name 1] & ".")),Trim([Material] & " " & [Type] & ".")))))))

You can replace the IIf() Functions with Nested If..Then..Else. .ElseIf..End If structures, something similar to the following: - If Not IsNull(Me![Name 3]) And Not IsNull(Me![Width]) Then
-
Me![Description] = Trim(Me![Material]) & " " & Me![Type] & " with " & Me![Name 1] & ", " & Me![Name 2] & _
-
" and " & Me![Name 3] & ". Approximately" & Me![Width] & "mm x " & Me![Height] & "mm."
-
Else
-
If Not IsNull(Me![Name 3] And IsNull(Me![Width]) Then
-
Me![Description] = Trim(Me![Material]) & " " & Me![Type] & " with " & Me![Name 1] & ", " & Me![Name 2] & _
-
" and " & Me![Name 3] & "."
-
ElseIf Not IsNull(Me![Name 2]) And Not IsNull(Me![Width]) Then
-
Me![Description] = Trim(Me![Material]) & " " & Me![Type] & " with " & Me![Name 1] & " and " & Me![Name 2] & ". " & _
-
"Approximately " Me![Width] & "mm x " & Me![Height] & "mm."
-
'Other Nested If/Else/ElseIf/End If structures where needed
-
End If
-
End If
