uicontrol popup 0 selection problem

The following piece of code is an extract of a function that I am currently developing.

The extract has 3 popup uicontrol selections A,B,C. A & C require that the user can select '0' or other values, B doesn't require selection of '0' from the popup.

When you click the generate button, the extracted values are output to the command window. With the default values selected (0,1,0) Why is it that A&C never output the selected value, they output selected value + 1, where B outputs the selected value?

    function [] = test()

    S.fh = figure('NumberTitle','off','Visible','on', 'Menu','none', 'Name','tst');
    movegui(S.fh,'center')

    S.mrSign = uicontrol('Style', 'popup',...
           'String', '0|1',...
           'Position', [20 340 100 50]);

    uicontrol('Style','text','Position', [20 400 100 15], 'String' ,'A')

    S.mrWl = uicontrol('Style', 'popup',...
           'String', '1|2|3|4|5|6|7|8|9|10|11|12|13|14|15|16|17|18|19|20|21|22|23|24|25|26|27|28|29|30|31|32',...

You are not popping up the selected value but the position of the selected value. Since you start at 0, it looks it pops up the selection plus 1.

that makes sense, thanks for that.
