Your old nested() function returned some HTML, but your new nested() function is printing its HTML before the main code has printed the header or anything else. The text printed by nested() is breaking your HTTP headers, which produces the result you're reporting.

Solution: nested() should return the HTML instead of printing it.

Note that running your CGI script from the command line probably would have revealed the problem.
