[Chimera-users] Question about using the volume command

Hi, The command volume #5 level 2.30 color 0.6,0.6,0.6 transparency 0.4 style solid doesn't work on my computer (OSX), Chimera (Version 1.7, build 38197) requests that "Solid level must be <data-value,brightness-level>". What am I doing wrong? Thanks for any suggestions, Henning.
