I'm attempting to search an entire tab for a specific name and if that name is found I would like an "X" to be displayed. Currently I'm using the following formula, but it appears that it is searching only a specific cell (rather than range) for the name. For example, I'm attepting to search the Jan11 for the name found in cell F11 and if found I would like to see an "X", if not, the cell will remain empty. I see the name I am searching for on the January tab, yet it is coming back with a blank cell, which implies the formula didn't find the text? Any ideas on how to correct?
=IF(ISNUMBER(SEARCH(F11,'Jan11'!A1:G50)),"X","")
=IF(ISNUMBER(SEARCH(F11,'Jan11'!A1:G50)),"X","")
