Hello
Create two names on sheet1:
"Product" to refer to product names in column A
"Price" to refer to prices in column B
Then in the CmdCost_CLick place this:

Private Sub CmdCost_Click()
If Me.txtQuantity.Value < "" Then
prod = Me.lboProduct.Value
Pprice = Application.WorksheetFunction.Index(Range("Price") _
, Application.WorksheetFunction.Match(prod, Range("Product"), 0))
MsgBox Pprice * txtQuantity
End If
End Sub

I have a lisbox(lboProduct) on a userform (UserForm3). The listbox
references
a list of products on a worksheet (Sheet1) in column A. In column B of
Sheet1
is the corresponding price of each product. The UserForm3 also has a
TextBox
(txtQuantity). I have a command button (cmdCost) that when clicked needs
to
show the total cost. Which is equal to the amount entered in txtQuantity *
the corresponding price of the product selected in the lboProducts.
