NO! NO! NO! NEVER USE GLOBAL VARIABLES FOR THIS SORT OF THING! OK, now that I've got your attention :) , please explain what you're trying to do with $gItems. There will be a more appropriate place to put it than in a global variable; we just have to figure out what it is.

Note, however, that Haml is generally a superior alternative to ERb, and in this case it provides an easier way to do this with its %tag[object] syntax. > > [code] > <table> > <tr> > <%for item in 0..$gItems%> > <td id="col" + item.to_s > > <%= "col" + item.to_s %> > </td> > <%end%> > </tr> > </table> > [/code] Best, -- Marnen Laibow-Koser http://www.marnen.org [email protected] -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
