Error Code:
—Reference to non-existent field 'shape1tx'.
—Error in Hoover_The_If_And_Switch2>process1 (line 109) set(S.shape1tx,'string','What is the radius of the Circle')
—Error while evaluating uicontrol Callback
-The error in the code is in the last else statement: else set(S.shape1tx,'string','What is the radius of the Circle')
-I cant not figure out what is wrong with it at all. When I comment of the —–entire else section, the problem just shifts to the next place where I try and -change the string in S.shape1tx. Please Help.
