使用Excel中的VBA，如何使用变量引用单元格

Question

正如标题所示，我无法弄清楚如何使用行的变量进入单元格。我附上了我目前拥有的代码，评论部分就是我遇到的问题，谢谢！

Private Sub Go_Click()
Dim id As Double
Dim qt As Double
Dim num As Double
Dim rngSearch As Range, rngFound As Range
id = Range("D4").Value
qt = Range("E4").Value
Set rngSearch = Range("A:A")
Set rngFound = rngSearch.Find(What:=id, LookIn:=xlValues, LookAt:=xlPart)
num = rngFound.Row
If rngFound Is Nothing Then
MsgBox "Stock ID Not Found"
Else
MsgBox rngFound.Row
'Range("O num.Value") = Range("O num.Value") - qt
End If
Range(rngFound.Row) = Range(rngFound.Row) - qt
End Sub

也许

Range("O" & num).value=Range("O" & num).value-qt
