Issue pulling data

[BJEaton79]

Hi, New to the forum and somewhat new to VB.net and .net for that matter. I'm working on a program that pulls data from two tables and performs calculations utilizing that data and some user input. I'm having a weird issue where this line of code is retrieving the wrong data from one of the tables on some occasions.

FormData.VLC1 = CSng(EngineDBDataSet.Tables(0).Rows(UnitComboBox.SelectedIndex).Item("Vlc1").ToString())

Thanks in advance,
Brian

I should clarify the combobox works as expected for a few of the rows but when row index 0 is selected the data either doesn't update to reflect the data in the first row or in some cases pulled data from the wrong column.
