Max Ntuple branches? (260)

Is it so that the maximum number of branches in an Ntuple is 260? I have a Ntuple with 320 degrees and it loads up without an error, but when I try this:
MyNTuple->Draw(“Branch261”);
I get the following error:
*ERROR 30 :
Bad numerical expression : "Branch261"
Is there a way around this?
I am using RetHat 9 with Root Version 3.10/02 16 December 2003
Thank you,

Hi,

There is no such limitation. Make sure you properly type your branch name (including casing). If this does not work, please try a more recent version of ROOT.

Cheers,
Philippe.
