Possibly in the wrong places as i think this question relates to some pretty old stuff.

I need to know if its possible to edit a function using another function by adding extra lines of code to it.

More specifically im looking at adding additional things to a drop down box. The major limitation I have here is that it needs to be coded using VBA specific to Excel 2002 (its a corporate edition afaik). Any suggestions?
