I tried to simplify the code so that it would be the simplest for asking the question. Maybe the full example of what I am trying to do would be better.

I understand what you are saying about refresh setting the state back to the default, but checkboxes stay checked, why do radio buttons reset?

This link will take you to the charting program that I am working on. If you select a column chart and hit refresh, everything works great. Then if you change ONLY the number of Months and refresh again, it resets the chart type to line.

Any suggestions for how to preserve the setting for columns? Neither the drop down nor the checkboxes seem to have the problem.

Thanks for the responses so far.
