Index across multiple sheets returning multiple values

Index across multiple sheets returning multiple values
Hi all,

I am building a payroll workbook and I need to build a sheet that will allow me to choose an employee name and the formula will return all the data related to this employee. I found this forumla to do this:
=IF(ROWS(...)<=...;INDEX(INDIRECT(...);SMALL(IF(...=...;ROW(...)-ROW(...)+1);ROWS(...)));"")

But in my workbook, the data is on multiple sheets . How do I adapt this formula to look into 12 sheets?

Hopefully, that data would be returned in order of the date of the pay.

Thanks for your help
