get(handles.uitable1,'Data') returns a cell array. You need to check to see if a particular cell is empty, for example
if isempty(data{1,1})

but if uitable1 has a value in case of error

If I'm reading this right, you have a cell array of error messages and you want to see if there are any messages in it. Your going to have to iterate through the cell array and check to see if each individual cell is empty.
