#FN_NOT_SUPPORTED - VLOOKUP & ISNA

#FN_NOT_SUPPORTED - VLOOKUP & ISNA

Hi, 

I have the following VLOOKUP reference working ok in Excel 2013 however an issue using Zoho Docs. I have change the "0" to FALSE however now instead of #FN_NOT_SUPPORTED i'm getting #NAME!

Here is the cell 

MS Excel =IF(ISNA(VLOOKUP($Q10,Interest!$D:$E,2,FALSE)),"",VLOOKUP($Q10,Interest!$D:$E,2,FALSE))
Zoho Conversion =IF(ISNA(VLOOKUP($Q10;interest!$d:$e;2;0));"";VLOOKUP($Q10;interest!$d:$e;2;0))

Zoho Amendment =IF(ISNA(VLOOKUP($Q10;interest!$d:$e;2; FALSE));"";VLOOKUP($Q10;interest!$d:$e;2; FALSE))

Can somewhere tell me what is wrong with this?

Thanks

J
