displaying calculation in a label

Ok i have an item from a combobox that has a set price which is displayed in lblprice. When information is entered into the txtqty i want it to take the lblprice and calculate that with the txtqty to equal lbltotal. It works fine for the first item(0) but when i delete the number in qty to change the qty it gives a type mismatch error 13. Also the price shows up for the other times but when i enter in a qty into the txtqty it doesnt calculate the lbltotal for the rest of the itmes.

I know its confusing but any insight will be appreciated. I dont know if index is even how you count how many txtbox items are in an array?


Private Sub txtQty_Change(Index As Integer)
Dim i As Integer

For i = 0 To txtQty(i).Index

lblTotal(i).Caption = FormatCurrency(txtQty(i).Text * lblPrice (i).Caption)


Next i
End Sub

nevermind i think i actually figured it out...at least for now
