QUESTION: Hey Tom,

I can see you have replied to 18350 questions. Thanks for contributing to this community.This is my first question and first vb code that i m trying to write.

Logic is :

if column c contains "yes" , column D and E cant be blank

Code should be like:

if ( C1= yes and D1 or E1 or both are blank , it should highlight the blank cell with color say light blue and with message box , these cells cant be blank)

else

do nothing

Till , last row , ie.e the column A contains values.

See if you can help me in this.

Thanks in Advance.

ANSWER: Dhwani,

this code was tested and worked for me according to my understanding of what you describe.

Test it on a copy of your workbook until you are satisfied it works as you desire.

Sub abcd()

Dim i As Long

Dim r As Range

Dim cell As Range

' starting with C1, find the last used cell in column C

Set r = Range("C1", Cells(Rows.Count, "C").End(xlUp))

' loop through those cells in column C

For Each cell In r

' check if the cell contains yes

If LCase(cell.Value) = "yes" Then

' check the cell to the right and the second cell

' to the right

For i = 1 To 2

' see if the cell is empty/blank

If Len(Trim(cell.Offset(0, i))) = 0 Then

' it is so color the interior light blue and put in

' a message that it can't be blank

With cell.Offset(0, i)

.Value = "Can't be blank"

.Interior.ColorIndex = 8

End With

End If

Next

End If

Next

End Sub

QUESTION: Hey Tom,

Based on my explanation you have done it perfectly.

But I think I explained it wrongly. Just one small modification , if there is any blank cell , it should change the color(already done by you)

now there can be 2 possibilities:

1. Any blank cell exists

Msgbox : Highlighted cell must contain a value , please correct

2. If no blank cell exists

Msgbox : good to go

Thanks for helping. Good day to You!!

Dhwani,

It is unclear where the message "good to go" should be placed. I will put it in column F

Sub abcd()

Dim i As Long

Dim r As Range

Dim cell As Range

Dim bBlank As Boolean

' starting with C1, find the last used cell in column C

Set r = Range("C1", Cells(Rows.Count, "C").End(xlUp))

' loop through those cells in column C

For Each cell In r

' check if the cell contains yes

If LCase(cell.Value) = "yes" Then

' check the cell to the right and the second cell

' to the right

' use a Boolean variable to track whether

' a blank cell is found

bBlank = False

For i = 1 To 2

' see if the cell is empty/blank

If Len(Trim(cell.Offset(0, i))) = 0 Then

' it is so color the interior light blue and put in

' a message that it can't be blank

With cell.Offset(0, i)

.Interior.ColorIndex = 8

bBlank = True

End With

End If

Next

If bBlank Then

cell.Offset(0, 3) = "Highlighted cell must contain a value, please correct"

Else

cell.Offset(0, 3) = "good to go"

End If

End If

Next

End Sub

--
