Activate different workbook to run macro

[asnkj23791]

I created a macro in my workbook using an active worksheet from another workbook. I would now like to run my macro, but use yet another different active workbook to get my data.

I have this line 20 times in my macro...

Windows("IFS_round_1").Activate

...so I do not want to change it (ex. IFS_round_2) each time I open a new workbook to run the macro. Is there something I can add so the macro just uses whichever active workbook I have open?

Thanks!
