You are probably missing a space between a and y, so your equation is different from the one in the help browser. Consider spending a little time studying Mathematica basics, will save you a lot of time in the future!

I am literally copying from its own documentation, and it still spits out failures. For example: In: DSolve[y''[x]==ay'[x]+y[x],y,x] DSolve::dvnoarg: The function y appears with no arguments Out: DSolve[y''[x]==(ay)/x+y[x],y,x] Wha?
