I have 2 Worksheets in my Workbook: Program_Data_Input & Program_Summary

In the Macro I have a line:
Range("A3:G300").Select
Selection.ClearContents

This clears fine when I am on the Program_Data_Input Woorksheet.
I never want to update the Program_Summary Worksheet (I've protected it just
in case).

If I were on the Program_Summary Worksheet and ran the macro there by
mistake (set to Ctrl+i) is there a way to hard code the macro to explicitly
clear the Program_Data_Input Worksheet regardless of which Worksheet I'm in?

I tried using this instead but got an error:
Worksheets("Program_Data_Input").Range("A3:G300"). Select
Selection.ClearContents
