Hi,
Can someone please explain for me why Txthotelcost.Text keeps coming out as 0....what should be happening is the correct hotel charge should be displayed for the selected hotel in my list box...
thanks In advance

Dim HotelName(4) As String
Dim hotelcharge(4) As Integer
-------------------------------------------------------------------
Private Sub CmdHotelInfo_Click()
For ix = 1 To 4
HotelName(ix) = InputBox("Enter Hotel Name")
hotelcharge(ix) = InputBox("Enter Hotel Charge Per Week")
Next
End Sub
-------------------------------------------------------------------
Private Sub CmdViewHotels_Click()
For ix = 1 To 4
LstHotels.AddItem HotelName(ix)
Next
End Sub
------------------------------------------------------------------
Private Sub LstHotels_Click()
HotelName(0) = LstHotels.Text
ix = Size
Do While HotelName(ix) <> LstHotels.Text
ix = ix - 1
Loop
Txthotelcost.Text = hotelcharge(ix)

Hi DaveChadwick,

An easier way is this:

Private Sub LstHotels_Click()
Txthotelcost.Text = HoteCharge(LstHotels.ListIndex + 1)
End Sub

The .ListIndex property of the list control tells you which one has been selected, this starts at zero so you need to add one to it.

I am assuming that you have Option Base 1 set for this program as otherwise your array will start at 0 and you are looping from 1 to 4 which would normally generate a subscript error.
