Error in formula

Error in formula

In Zoho sheet,
when i try to insert formula like - "=IF($C$2="","",INDEX(Age,MATCH($C$2:Name,0)))"
it gets converted as - "=IF($C$2="";"";INDEX(Age; MATCH($C$2;Name;0)))"
i mean all , (commas) are converted to : (semicolon) and then in cell i see message - #REF!.
Any Solution ?
