In the Tutorial it is writen that "maxv" is the function for maximun in Lite C. However it gives an error when compiling the following:

vars H1 = series(priceHigh(36));
vars H2 = series(priceHigh(35));
vars H3 = series(priceHigh(34));
vars H4 = series(priceHigh(33));
vars H5 = series(priceHigh(32));

vars A11 = maxv (H1[0],H2[0],H3[0],H4[0],H5[0]);

It gives and error saying that "maxv" is not defined. Can anyone tell me where the mistake is? The idea is to get the High from High 36 to High 32.
