Hi, I'm trying to get the value that's in the variable but I can only get to the name of the variable and not the actual value. Thank you
w = getfield(evalin('base','whos'),{13,1},'name')
w = Variable

What workspace are you trying to import this variable (that lives in the base workspace) into? The workspace of one of your functions? How did a variable get into the base workspace anyway? Did you run a script and it left the variable in the base workspace, and now you're running a function, which has its own local workspace, and now you want to import the variable that your script left in the base workspace into the workspace of your function? If what I said totally confused you then you need to read up on workspaces. Also, look at the FAQ: http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.28s.29.3F

Trying to transport variables magically remote controlled is obviously a bad idea. Although it might work, I recommend not to do this:
w = getfield(evalin('base','whos'), {13,1}, 'name')
value = evalin('base', w)
Brrr. You would suffer.
