Formula: =IF((ISNUMBER(SEARCH("172.29.90.",$A3)))*(ISNUMBER(SEARCH("00-00-85",$F3))),"MF

Hi,

I am having issue with formula

=IF((ISNUMBER(SEARCH("172.29.90.",$A3)))*(ISNUMBER(SEARCH("00-00-85",$F3))),"MF"&LEFT([@Location],3),
IF((ISNUMBER(SEARCH("172.29.92.",$A3)))*(ISNUMBER(SEARCH("00-00-85",$F3))),"MF"&LEFT([@Location],3),
IF((ISNUMBER(SEARCH("172.29.84.",$A3)))*(ISNUMBER(SEARCH("00-00-85",$F3))),"MF"&LEFT([@Location],3),
IF((ISNUMBER(SEARCH("172.29.74.13",$A3)))*(ISNUMBER(SEARCH("00-00-85",$F3))),"MF"&LEFT([@Location],8),
IF((ISNUMBER(SEARCH("172.29.80.",$A3)))*(ISNUMBER(SEARCH("00-00-85",$F3))),"MF"&LEFT([@Location],3),
IF((ISNUMBER(SEARCH("172.29.96.",$A3)))*(ISNUMBER(SEARCH("00-00-85",$F3))),"MFICV"),
"Unknown"))))))

Column E is hidden in my spreadsheet - $A3 and $F3 are correct

Error message: You've entered too many arguments for this function.

Any guide would be highly appreciated
