I have this spreadsheet with a button at the top that runs a macro (I assume) to add a row to a list of contacts. Since the original macro was created, I have added columns of additional information to the spreadsheet. So now, when I use the button to add a contact it only shifts the first 8 columns of information. I want to edit this to have it include the additional columns. However, when I go to Tools-Macros and select the macro in question, I do not get the option to edit it (grayed out). I've checked the worksheet security and the macro security, to no avail. What else could be keeping me from being able to edit this macro?
