Use VBA to load a input window (table) in ie?

I'm trying to automate something using vba and internet explorer.

I know how to fill in data and click on buttons, but I'm struggling figure out how to click on a java button that I need to in order to fill in the data.

If I put the mouse over the button it says ""javascript:void();" If I click on it then it brings up a form where I can enter data and hit submit.

When I look at the source code I see things like:

div id
src
href="javascript:void();"
onclick="showWhatIneed)" 
title="What I need"

I also see references to table in the source code, so my guess is I somehow need to tell it to display the table.

What am I looking for or what kind of code would I use to display the area I need to put in the input?

Any help would be greatly appreciated
