Compile Syntax Error - unsure whats wrong with Autofilter Label Macro

Hello,

Using MS Office 2003 on Mac & I am getting Compile Syntax Error and my Sub Name is being highlighted YELLOW & all those rows listing the Autofilter Actions are highlighted RED. It not even executing the first action, the column Insert.

Could someone please take a look & let me know if anything is obviously wrong - maybe I've been looking at it too long.

Greatly appreciate your help & insight.
