Sahi not working on more than one javascript function

geo

hi
i have two javascript functions in my code like

browser.setBrowserJS("function input(){var inputFields = new Array();inputFields=document.getElementsByTagName('input');
return inputFields;}"); and second javascript function

browser.setBrowserJS("function div(){ar divFields = new Array();divFields=document.getElementsByTagName('div');
return divFields;}");


System.out.println("value="+ browser.fetch("input()"));

System.out.println("value="+ browser.fetch("div()"));

I can execute the first function , but the call to second function throws error like

error:_sahi.setServerVarPlain('___lastValue___Tue Feb 14 17:45:27 IST 2012', div())
TypeError: Object expected
