I found a solution to my problem, if anybody is wondering here it is, sorry for my amateur-ness! This actually kinda is a better answer than anything I could have come up with (except the fact that I found this answer by myself:
if ComboBox.SelectedItem().Equals("any choice of one of the items") = True Then
'execute command!
The above was the syntax, I got an example of my code below:
if ClientBox.SelectedItem().Equals("Agentleader1 (Leader)") = True Then
TEA = "****" 'That's my email!
Hope this helped to anybody that couldn't figure out how to find whether a specified item that is selected in a certain combo-box is selected!
