From my macro how to call the Add ins ->"Addin_Name"

[sutha_anbu]

From my macro i wanted to automate the clinking(run) of Addin -> "Tool Name", I am opening the respective Excel file and then calling for the Addin -> Tool name. e.g>Application.Run "'" & fileName & "'!RadarUpdate", but it does not works
May I know how to invoke from my Macro the Addin -> ToolName(RadarUpdate) click. Is there any way to find what is the macro function the "Radar Update" calls?
Help is appreciated.
