Using MAX() ignoring last 5 bars

[hunter]

I can not see why this simple code is not returning a value.

Plot0.Set(MAX(High, 10)[5]);

If I use an index value of 0 I get values.
Plot0.Set(MAX(High, 10)[0]);

Thanks.

Thanks Bertrand,

The info in your link has resolved my issue.
I just installed the software yesterday and it has been a very long time since I did any programing.
I hope all my questions are that easy to solve.
