Return value from a UITABLE

Hi All,
Does anyone know if there is a way to search for a specific value in a UI Table and return the value in the column next to it?
I am using a GUI and the user selects a value from a lsitbox and I would like to look for that selected value in the 3 column UITABLE that is in the GUI (that already has data in it) and return the value in the column next to it.
They value being searched for is always in column 1 of the UITABLE (if that helps at all).
Any help is appreciated!!
Rob

curdata = get(handles.uitable, 'data');
tf = ismember(curdata(:,1), ValueToLocate);
adjacent_value = curdata(tf, 2);
if numel(adjacent_value) ~= 1
error('match fail');
end
This would probably leave you with a 1 x 1 cell, so use adjacent_value{1}

Are the uitable entries in a different order? If not, then the entry you want is
curdata{rownumber, 2}

No they are in the same order. Walter, I was actually able to get this working using a response from you on another thread (go figure! http://www.mathworks.com/matlabcentral/answers/24300):
strings = get(hObject, 'string');
curval = get(hObject, 'value');
if iscell(strings)
curstring = strings{curval};
else
curstring = strings(curval, :); %char array
end
Thanks for all the help!

Get the table data:
tableData = get(handles.table1, 'Data');
You might have to use cell2mat(tableData) - I don't remember. Then use extract the column you're looking for and use ismember() or find() to find the matching value. Be sure to know the FAQ. So you might want to do
theColumn = tableData(:, 1); % Get column 1
row = find(abs(theColumn - theSoughtValue) < 0.00001);
Then just get the next column.
theValueWeWant = table(row, 2);
