Draggable GUI help

[Kinjiru]

Ok so I followed this tutorial here http://www.touchofdeathforums.com/smf/index.php/topic,67261.0.html
And things went well for the first few menus i tryed, but when I moved on to the spells and inventory I get a compile error because the procedures already exist.

I did some digging on the forum and found this quote
@Robin:

> It'll only drag the items/skills if your mouse is hovering over one. If the 'IsInvItem' check is returned negative, simply call the drag system instead.

So i need to insert the drag codes in the following Subs where the IsInvItem is returned negative, but im not sure where that is

```
Private Sub picInventory_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
    Dim InvNum As Long

    ' If debug mode, handle error then exit out
    If Options.Debug = 1 Then On Error GoTo errorhandler

    InvNum = IsInvItem(X, Y)

    If Button = 1 Then
        If InvNum <> 0 Then
            If InTrade > 0 Then Exit Sub
            If InBank Or InShop Then Exit Sub
            DragInvSlotNum = InvNum
        End If

    ElseIf Button = 2 Then
        If Not InBank And Not InShop And Not InTrade > 0 Then
            If InvNum <> 0 Then
                If Item(GetPlayerInvItemNum(MyIndex, InvNum)).Type = ITEM_TYPE_CURRENCY Then
                    If GetPlayerInvItemValue(MyIndex, InvNum) > 0 Then
                        CurrencyMenu = 1 ' drop
                        lblCurrency.Caption = "How many do you want to drop?"
                        tmpCurrencyItem = InvNum
                        txtCurrency.text = vbNullString
                        picCurrency.Visible = True
                        txtCurrency.SetFocus
                    End If
                Else
                    Call SendDropItem(InvNum, 0)
                End If
            End If
        End If
    End If

Ok so I got the code added in but its not working, the inventory is still not moving

```

    Dim InvNum As Long

    ' If debug mode, handle error then exit out
    If Options.Debug = 1 Then On Error GoTo errorhandler

    InvNum = IsInvItem(x, y)

    If Button = 1 Then
        If InvNum <> 0 Then
                XM2 = x
                XM2 = y
            If InTrade > 0 Then Exit Sub
            If InBank Or InShop Then Exit Sub
            DragInvSlotNum = InvNum

        End If

    ElseIf Button = 2 Then
        If Not InBank And Not InShop And Not InTrade > 0 Then
            If InvNum <> 0 Then
                If Item(GetPlayerInvItemNum(MyIndex, InvNum)).Type = ITEM_TYPE_CURRENCY Then
