Perhaps the buttons are in a disabled state for some reason for example, imagine a "Continue" button which is not click-able until a check box marked "I have read, understand and agree to the license agreement" is checked.
It's unlikely that anyone here can help (outside providing truisms) unless you provide more data. You've provided no code or spy.pl output and provide no details of the application you're trying to automate. I suggest this is something you spend time debugging in conjunction with a coworker familiar with the application and automation, in such circumstances asking others to speculate what the problems may be isn't a productive use of anyone's time IMHO.
Update: please mark updates to your posts, read and understand How do I post a question effectively?.
