does anyone know how to add the following values together?

00:00:10

00:10:40

02:40:20

etc..

basically they are timespan values written to the database indiviually and now that i recall them - i am having difficulty adding them together to get a total Value.

i was using this:

Dim qty, price As Decimal

qty = Val(Me.TextBox1.Text)

price = Val(Me.TextBox2.Text)

TextBox3.Text = qty * price

the problem occurs with the ":" - but i cannot figure a way around it.
