Ayuda con la clase AnimTween

[magistr]

Buenos días soy un poco principiante en eso del actionscript y tengo un problema ke me trae de cabeza a ver si alguno de vosotros me puede ayudar. Resulta que tengo una clase animtween y al generar el swf me da el siguiente error:

1084: Error de sintaxis: se esperaba identifier antes de this.

el codigo es este y el error me da en la linea que esta en rojo. alguien me puede ayudar.

muchas gracias
