You were using a fraction as a variable name. The independent variable in the domain specifier is repeatedly assigned values and you can't assign values to a fraction (example: t/tf = 0).

I second Bill's comment that subscripts take work to do right. You can start by reading
http://reference.wolfram.com/mathematica/Notation/tutorial/NotationSymbolizeAndInfixNotation.html,
about 60% of the way down, about the Symbolize function and the Notations Palette. A notebook Tech Support sent me about making subscripted variables is attached.
