Ah, good point. I guess for some reason I was under the assumption that it was required to make a new one

The frame was in another class, however the

event.getSource().getTopLevelAncestor()

Worked perfectly, I see what was going wrong now. Thanks!

Disregard that last post, I believe I've finally figured it out and am implementing the conversions based on the boxes checked!

I mean it is, I understand what it does I was just trying to relate that to the code I have already written. Took a year off so I am a tad rusty. I tried to implement your example into my own and created more errors and problems.

I'm at a theatrical flashing red light, I'm not sure where to turn now. Here are my two code files, would you mind giving me a few suggestions about doing something similar above that would work into what I have?

baseconversion.java: (This is the file that builds the GUI so to speak)

}

I hope this isn't info-overload.. feel free to pick it apart too if your up to it. Should my text field and converting button be in the second file rather than the first?

I can't thank you enough, could you give me a quick walk through of that code
