Calculating ComboBox Columns

37 32bit
Back again...

I'm trying to calculate two TextBoxes which contain a values from a ComboBox Columns.

TextBox1 - txtQty (Control Source: equals [cboCaliber].[Column](3)
TextBox2 - txtPicked (Control Source: equals [cboCaliber].[Column](4)
TextBox3 - txtActQty (Control Source: equals [txtQty]minus[txtPicked]

When Form loads txtQty and txtPicked have the right values but txtActQty just shows #Error.

I don't know if you can calculate the results of a ComboBox Columns.
