Next Without For Error VBA - excel

Question

I have the following code and VBA is giving me a "Next Without For" Error when I definitely have both. I know that VBA can list errors that are not exactly the same as what it says they are, but I can't find any other closed loops. If someone could check this out, that would be awesome! Thanks:
Option Explicit
Sub HW09()
Dim ng As Integer
Dim v As String
Dim lg As String
Dim ca As Integer
Dim sd As Integer
Dim c As Integer
Dim r As Integer
c = 2
Do
ng = InputBox("Please enter the student's numerical grade.")
If ng < 0 Then
ng = 0
If ng > 100 Then
ng = 100
End If
Cells(c, 2).Value (ng)
c = c + 1
v = InputBox("Would you like to enter another grade? Type 'Y' for yes and 'N' for no.")
If v = "N" Then Exit Do
End If
Loop
Cells(1, 2).Value ("Numerical Grade")
Cells(1, 1).Value ("Letter Grade")
For r = 1 To c
If Cells(r, 2) >= 90 Then
lg = "A"
Cells(r, 1).Value (lg)
If Cells(r, 2) >= 80 Then
lg = "B"
Cells(c, 1).Value (lg)
If Cells(r, 2) >= 70 Then
lg = "C"
Cells(c, 1).Value (lg)
If Cells(r, 2) >= 60 Then
lg = "D"
Cells(c, 1).Value (lg)
Else
lg = "F"
Cells(c, 1).Value (lg)
End If
r = r + 1
Next r
c = c - 1
ca = Application.WorksheetFunction.Average("(1,2):(1,c)")
If ca >= 90 Then
lg = "A"
If ca >= 80 Then
lg = "B"
If ca >= 70 Then
lg = "C"
If ca >= 60 Then
lg = "D"
Else
lg = "F"
End If
MsgBox ("The average letter grade for these " & (c) & " students is " & (lg) & ".")
sd = c * (Application.WorksheetFunction.Sum("(1, 2)(1, c) ^ 2)")-Application.WorksheetFunction.Sum("(1, 2)(1, c)") ^ 2 / (c * (c - 1)))
MsgBox ("The standard deviation for these grades is" & (sd) & ".")
End Sub

Answer 1

Your problem is you are doing If... Then... If... Then... instead of If... Then... ElseIf... Then...
If Cells(r, 2) >= 90 Then
lg = "A"
Cells(r, 1).Value (lg)
ElseIf Cells(r, 2) >= 80 Then
lg = "B"
Cells(c, 1).Value (lg)
ElseIf Cells(r, 2) >= 70 Then
lg = "C"
Cells(c, 1).Value (lg)
ElseIf Cells(r, 2) >= 60 Then
lg = "D"
Cells(c, 1).Value (lg)
Else
lg = "F"
Cells(c, 1).Value (lg)
End If

Answer 2

Every IF statement needs to be terminated with an ENDIF.
Within the FOR/NEXT loop you have 4 IFs, one ELSE and one ENDIF
this needs to be changed to:
IF Condition1 THEN
'code
ELSEIF Condition2 THEN
'code
ELSEIF Condition3 THEN
'code
ELSEIF Condition4 THEN
'code
ELSE 'All other possibilities
'code
ENDIF

Answer 3

I think the nested If statements inside For r = 1 to c... don't close properly? Generally, each If also requires an End If, and you only have one End If statement. This is causing the compiler to reach the Next r statement while it's still "inside" an If block, thus the error raises, and makes sense.
You may look in to using a Select Case switch instead of nesting several If/Then statements. In my experience, they're more easy to interpret when you're debugging. Something like:
For r = 1 To c
Select Case Cells(r,2)
Case >= 90
lg = "A"
Case >= 80
lg = "B"
Case >= 70
lg = "C"
Case >= 60
lg = "D"
Case Else
lg = "F"
End Select
Cells(r,1).Value = lg
r = r + 1 '## You may want to omit this line, see my comments.
Next r
Note: You may want to omit the r = r+1 unless you're intending to skip every other record, the Next statement automatically increments r by a value of 1 unless otherwise specified.
If you do intend to skip every other record, you should do For r = 1 to c Step 2 and likewise omit the r = r+1 .

Answer 4

This error occurs when the condition is not closed.
You must don't forger close if conditions.
for example:
Public Sub start_r()
LastRow = SPT_DB.Range("D" & Rows.count).End(xlUp).Row
Dim i As Long
For i = 3 To 132
State = Cells(1, i)
Dim j As Long
For j = 2 To LastRow
m = SPT_DB.Cells(j, 4).Value
z = SPT_DB.Cells(j, 5).Value
n1 = SPT_DB.Cells(j, 6).Value
fc = SPT_DB.Cells(j, 7).Value
am = SPT_DB.Cells(j, 8).Value
sp = SPT_DB.Cells(j, 10).Value
sr = SPT_DB.Cells(j, 11).Value
liq = SPT_DB.Cells(j, 13).Value
num1 = Val(Left(State, 1))
num2 = Val(Mid(State, 3, 1))
num3 = Val(Mid(State, 5, 1))
num4 = Val(Mid(State, 7, 1))
num5 = Val(Mid(State, 9, 1))
Dim spt_class As spt_class
Set spt_class = New spt_class
