Expression problems in new AE??

Hi guys,  I'm trying to add an expression to my type layer in After Effects and I keep getting an error for line two?

Does anyone see what could be wrong with this expression? It seems so basic.

Thanks for your help!!

HERE IT IS:

L = text.sourceText.length;

It = time – thisLayer.inPoint;

T = It*effect(“Speed”)(“Slider”);

F = Math.round( It % 1);if(F==1 |(T0)){Fl=”|”;}else{Fl=” “;}substr(0,T) + Fl
