I am working with a combo box and trying to assign a value to the combox.index

Code (gambas)

1.  ComboBox1.Index = ComboBox1.Count
2.   Print ComboBox1.Index, ComboBox1.Count
3.  
4. out put is   -1         7
5.  
6. ......
7.  
8. Dim x As Integer = ComboBox1.Count
9.   ComboBox1.Index = x
10.   Print x, ComboBox1.Index, ComboBox1.Count
11.  
12. output is   7       -1        7
13.

16. You can only set the ComboBox.Index to integers in the legal range for the current condition of the combobox.
17.  
18. For example, if I create a new combobox and do this;
19.  
20. [code numbers="1" param="gambas" scroll="1"]  ComboBox1.Add("one")
21.   ComboBox1.Add("two")
22.   ComboBox1.Add("three")[/code]
23.  
24. I now have 3 items in the combobox, so the .Count = 3  and when .Index = 0 the Item is "one"
25. When you attempt to set .Index to 3 you get an error (or -1 value) because .Index = 3 would be the 4th Item, which does not exist.
26.  
27. I hope this is clear, but let me know.

thank You …. all I needed was .count -1 to get what i wanted  
The proverbial off by one error.
I have been struggling with this for two day.
