Your figure (or gui) is closed that's why this error occured

It looks like you have some text type object on figure like title,xlabels,ylabels, ...etc

what you are trying to do is setting the textproperty 'string' equal to variable low but when MATLAB tries to access the object whose handle is passed to it, it didn't find any thing so it gives you that error.
