problem when input a value in function which called from gui

hi,

I created gui for my work, I have a function when I called within GUI I HAVE TO INPUT A VALUE USING

prompt={'Enter the lenfgth of recommended list:'};
 title='length of recommendation list'; 
 answer=inputdlg(prompt,title);
 m = str2num(answer{1});

when input a value, the code is not running.

I tried to run the code without call it from gui, I did not find any problem.

I hope to know the reason. I would like to say when running the function the command window return message tell me that function is case sensitive

title() is the name of one of MATLAB's graphics routines; it is not advised that you use it a variable name.

Which function does it complain about the case sensitivity? Which file name (exactly) do you save it in, and what exactly is the "function" line for it ?

I changed the name but the problem still there.
