[code] LB.DeleteAllRows

If ComboBox1.listIndex = 0 Then
If ComboBox4.Listindex = 0 Then
LB.AddRow(“Carbon”, 3, 0, 0, 1, 1, 0, 0) 'Glycerol Selected
else
LB.AddRow(“Carbon”, 3, 0, 0, 1, 1, 0, 0) 'Glycerol Selected with MG1655
end If
else If ComboBox1.listIndex = 1 Then
If ComboBox4.Listindex = 0 Then
LB.AddRow(“Carbon”, 6, 0, 0, 1, 1, 0, 0) 'Glucose Selected
else
LB.AddRow(“Carbon”, 6, 0, 0, 1, 1, 0, 0) 'Glucose Selected with MG1655
end if
else
If ComboBox4.Listindex = 0 Then
LB.AddRow(“Carbon”, 5, 0, 0, 1, 1, 0, 0) 'Arabinose Selected
else
LB.AddRow(“Carbon”, 5, 0, 0, 1, 1, 0, 0) 'Arabinose Selected with MG1655
end if
end if[/code]

A listbox only accepts strings.
Try
LB.AddRow(“Carbon”, “3”, “0”, “0”, “1”, “1”, “0”, “0”) 'Glycerol Selected

Yep it worked thankyou
