I have been changing the pattern of a machine program, which originally built with flat sequence structures, to a state machine form. However, I have faced a problem like shown below. As you see in the picture, the old version and the new version have the same set, but the results are different. I assume that the space(it is empty space in the picture but sometimes it comes with "%" character) before the value gives me "0" but I have no idea where that space from or how to get rid of the space. Please help me!
