Why does this problem occur?

I have a callback function in a gui in which i am loading a file with two fields. When i run only that(callback function) part of the code, the fields get loaded in the work space. But when i run the entire code, the work space does not show the fields to be loaded. I didn't get any error either.

"the fields get loaded in the work space"

Which workspace: the callback's own workspace, another workspace in the GUI, or some unrelated workspace? How are you checking this: are you using the debugging tools?

thank you sooo much. I was struggling with this for a long time. You helped me solve it. Now my next problem is once the fields have been assigned to the base work space how can I use it in another callback function? I tried passing it as an argument and ended up getting "unknown variable error".

If you are using GUIDE then use guidata. If you are sensibly writing your own code then use nested functions.
