Adding Combo Boxes with numbers in their collection.

I have two combo boxes, each with a collection from 0 - 10. A number has been generated using the randomize() function - between 1 - 20 and is shown in a label.text. My problem involves the combo boxes not actually 'adding up' like numbers should. Maybe because they aren't actually number at all, I'm not sure. So for example, the random number equals to 10. You use the dropdown boxes to find the numbers that equal to 10. And so after that, when you click - I guess, an 'Enter' button, it doesn't equal. I've been using this code: If Combobox1.SelectedItem + Combobox2.SelectedItem = label3.text then msgbox("correct") end if Am I on the right track?

Thanks. We'll let you know when a new response is added.

Try converting the strings to integers:

<pre><b>Convert.ToInt32</b>(ComboBox1.SelectedItem) + <b>Convert.ToInt32</b>(ComboBox2.SelectedItem)

</pre>
