VBA in Excel: Runtime Error 1004 - excel

Question

I am trying to do the following. I have several spreadsheets that are named something like "ITT_198763" where the ITT part stays the same but the number changes. I also have one tab called program where the 6 digit number is imported on row 40 (hence the RngToSearch below). I need the program to 1) find the "ITT" sheet for a certain 6 digit number, 2) identify the corresponding row in the "Program" tab, and copy information from the "ITT" tab to row 41 of the identified column. I will be copying more information from the ITT sheet to the specified column, but for now I am just trying to get it to work once.
From the MsgBox, I know it identifies the correct prjNumber (the 6 digit number), but I get the runtime 1004 error on the line Set RngDest. Any help will be appreciated!
Sub Summary_Table()
Dim wks As Worksheet
Dim RngToSearch As Range, RngDest As Range
Dim foundColumn As Variant
Dim prjNumber
For Each wks In ActiveWorkbook.Worksheets
If ((Left(wks.Name, 3) = "ITT")) Then
prjNumber = Right(wks.Name, 6)
MsgBox (prjNumber)
Set RngToSearch = Sheets("Program").Range("C40:q40")
foundColumn = Sheets("Program").Application.Match(prjNumber, RngToSearch, False)
With Sheets("Program")
Set RngDest = .Range(1, foundColumn) 'Project Name
End With
If Not IsError(foundColumn) Then
wks.Range("E2").Copy RngDest
End If
End If
Next wks
End Sub
I tried the .cell instead with the following code (all else is the same) and now get runtime error 13 on the Set RngDest line:
Set RngToSearch = Sheets("Program").Range("C40:q48")
foundColumn = Sheets("Program").Application.Match(prjNumber, RngToSearch.Rows(1), False)
With Sheets("Program")
Set RngDest = RngToSearch.Cells(1, foundColumn) 'Project Name
End With

Answer 1

Yuo are getting that error because foundColumn has an invalid value. Step through the code and see what is the value of foundColumn
Here is an example which works.
Sub Sample()
Dim RngDest As Range, RngToSearch As Range
foundColumn = 1
Set RngToSearch = Sheets("Program").Range("C40:q40")
Set RngDest = RngToSearch.Cells(1, foundColumn)
Debug.Print RngDest.Address
End Sub
Add MsgBox foundColumn before the line Set RngDest = RngToSearch.Cells(1, foundColumn) and see what value do you get. I guess the line
foundColumn = Sheets("Program").Application.Match(prjNumber, RngToSearch, False)
is not giving you the desired value. Here is the way to reproduce the error.
EDIT (Solution)
You need to handle the situation when no match is found. Try something like this
Sub Sample()
Dim RngDest As Range, RngToSearch As Range
Set RngToSearch = Sheets("Program").Range("C40:q40")
foundcolumn = Sheets("Program").Application.Match(1, RngToSearch, False)
If CVErr(foundcolumn) = CVErr(2042) Then
MsgBox "Match Not Found"
Else
Set RngDest = RngToSearch.Cells(1, foundcolumn)
'
'~~> Rest of the code
'
End If
End Sub

Answer 2

You are looking for the Cells function, which has the prototype .Cells([RowIndex], [ColumnIndex]). The Range function takes either a string with a range name (like "A1", or a named range), or other range references.

Answer 3

I figured it out! Found column was the problem. Combining that with the help from the other commenters, the following works:
Sub Summary_Table()
Dim wks As Worksheet
Dim RngToSearch As Range, RngDest As Range
Dim foundColumn As Variant
Dim prjNumber
For Each wks In ActiveWorkbook.Worksheets
If ((Left(wks.Name, 3) = "ITT")) Then
prjNumber = Right(wks.Name, 6)
MsgBox (prjNumber)
Set RngToSearch = Sheets("Program").Range("a40:q48")
foundColumn = Sheets("Program").Rows(40).Find(what:=prjNumber, LookIn:=xlValues, lookat:=xlWhole, MatchCase:=False).Column
MsgBox (foundColumn)
With Sheets("Program")
Set RngDest = RngToSearch.Cells(2, foundColumn) 'Project Name
Debug.Print RngDest.Address
End With
If Not IsError(foundColumn) Then
wks.Range("E3").Copy RngDest
End If
End If
Next wks
End Sub
