Need a bit help with getting values from gui listbox

Hi guys!

I have a gui witha listbox with 3 values in it (0.01, 0.1 & 1).I need my gui to use numerical value selected in the listbox but I am having a bit of a trouble with it. I tried the following:

 timeStep = get(str2double(handles.listBox, 'String'));

but matlab gives me the following error:

 Error using str2num
 Too many input arguments.

I might be wrong, but it seems like it tries taking all 3 of the string values instead of the selected one. Any idea how to fix this??

Thank you !

The error message contains "str2num", but the code "str2double"?

The other way around: Get the string at first and convert it to doubles afterwards:

str2double(get(handles.listBox, 'String'))

It still takes all 3 values from the listBox. How can I make it take onl the selected one?
