I started to read this last night from home, and immediately thought "I didn't select ALL the cells!" .. but looking at it more closely this morning, I clearly did. While I was intending to select all cells in order to autofit the columns, like you siad, my very next statement for conditional formatting started with 'Selection.FormatConditions'... So it was working off of the whole worksheet.
I received these statements simply by 'recording' my actions with record macro- per usual. Then I try to apply it to my master TimelineExport code (by the way, I even took my code and copy/pasted it into a NotePad for safe keeping so I don't screw it up some day

. Especially because I had it 100% working smoothly, and now I'm trying to incorpoarte one more thing to it- so I figured I would save the GOOD version somewhere safe!).
Anywho, yes, with my new understanding I will now try to apply to the code and see if it works. I'll let you know how it turns out!
