okay, i have 1 workbook with 4 sheets. Sheets names are say, sheet1, sheet2, sheet3 and sheet4.

on sheet4, i want to create a formula that will pull rows B2 to H2 from sheet1, B2 to H2 on sheet2 and B2 to H2 from sheet3 (it will be a STDEV formula)



i've come up with:

=STDEV('sheet1'!B2:H2)
which will pull the info from sheet1, but i can't figure out how to add in the data from the other 2 sheets. is it possible? if so, how?

any help would be greatly appreciated
