I asked him to create a diagram but the Diagram (output) he created had a problem, I can’t see it. Instead, the “Preview” screen is displaying the following message in red :

Parse error on line 2: ... Chain Performance\n(Transport & Distrib -----------------------^ Expecting 'SQE', 'DOUBLECIRCLEEND', 'PE', '-)', 'STADIUMEND', 'SUBROUTINEEND', 'PIPE', 'CYLINDEREND', 'DIAMOND_STOP', 'TAGEND', 'TRAPEND', 'INVTRAPEND', 'UNICODE_TEXT', 'TEXT', 'TAGSTART', got 'PS'

Here is the entire code, please fix it as soon as possible, I really need that diagram now :
