Thank you Harry,
I think I understand what you're saying, but I'm not sure how to implement this.
My sheets are basically - Summary, 11, 22, 33, 44, 55. Column B is populated via VB script with the sheet names, and used as a reference in the hyperlink in column A, with row 1 having headers. How would I put in the reference you suggested?
COLUMN A COLUMN B
(Row 2)=HYPERLINK("[Ticket tracking.xlsm]'"&B2&"'!A2",B2) 11
(Row 3)=HYPERLINK("[Ticket tracking.xlsm]'"&B2&"'!A3",B3) 22
(Row 4)=HYPERLINK("[Ticket tracking.xlsm]'"&B2&"'!A4",B4) 33
(Row 5)=HYPERLINK("[Ticket tracking.xlsm]'"&B2&"'!A5",B5) 44
(Row 6)=HYPERLINK("[Ticket tracking.xlsm]'"&B2&"'!A6",B6) 55
