Finding Text And Clicking It On Screen

[MadQuestion]

I have a question for the text capturing experts in this forum, prob easier than I think but its not clear for me to really understand.
I am using a custom dialog with IE embedded in it and I allow a TextBox to allow the entry of any text, I turn this text into a variable called %SEARCHTEXT% I then want to search within the window for the text variable and click on it when/if found. I have never done anything like this task before so was hoping some kind coder could perhaps give me an example script with instructions for how to start? Im a text capture newbie!
