Try this function ... works for all the cases you listed:


Public Function mGetFirstNumber(sStr As Variant) As Variant

''
''  FW: 1 xxxxxxx - Approved
''  RE:  3 xxxxxxx - Denied
''  1 xxxxxxx -Approved
''  abcdefghi9
    If IsNull(sStr) Then Exit Function
   
    If IsNumeric(Left(sStr, 1)) Then
        mGetFirstNumber = Left(sStr, 1)
        Exit Function
    End If
   
    Dim iCnt As Long
    For iCnt = 1 To Len(sStr)
        If IsNumeric(Mid(sStr, iCnt, 1)) Then
            mGetFirstNumber = Mid(sStr, iCnt, 1)
            Exit Function
        End If
    Next iCnt

End Function

You can use Val(YourString)

Now, when you say First Number ... val() will return N number of digits at the start of a string ... except ... if the first digit is zero AND there are more digits after that, the zero will get dropped.

Is the number always the first character in your string ?

If so .... the just Left(YourString, 1)

varString = "Re: 1 xxx"

For x = 1 to Len(varString)
   if IsNumeric(Mid(varString, 1, 1)) = True Then FirstNumber =  Mid(varString, 1, 1)
   exit for
Next

If you're looking for more than a single digit number or potentially more, then we need to do a little more work.

Dim varstring As String
Dim firstnumber As Integer

varstring = "re: 3 xxxxx"
For x = 1 To Len(varstring)
   If IsNumeric(Mid(varstring, 1, i)) = True Then firstnumber = Mid(varstring, 1, i)
 
   Exit For
Next
  MsgBox (firstnumber)

The above returns a 0

Do you want "first number" or "first digit"?

The above returns a 0

In both comments, you're using "For x =...", but you never use 'x' anywhere within the loop. In the first comment, you use 'Mid(varstring, 1, i)'. Try using 'Mid(varstring, x, 1))' instead.

I want the first number.  This still returns a zero.  Thanks for your help!

Dim varstring As String
Dim firstnumber As Integer

varstring = "re: 3 xxxxx"
For x = 1 To Len(varstring)
   If IsNumeric(Mid(varstring, x, 1)) = True Then firstnumber = Mid(varstring, x, 1)
 
   Exit For
Next
MsgBox (firstnumber)

I tried this too:

If IsNumeric(Mid(varstring, 1, x)) = True Then firstnumber = Mid(varstring, 1, x)

I am pulling data out of the subject line of an Outlook message:

FW: 1 xxxxxxx - Approved
RE:  3 xxxxxxx - Denied
1 xxxxxxx - Approved

I want to pull the first number, 1,3,1

Thanks!
