Conversion failed when converting date and/or time from character string

Hi,

I am trying to run the following select statement and receive this error.

select convert(date,convert(varchar,FiscalYearId)+'-'+convert(varchar,FiscalMonthOfYearID)+'-01')
from ods.common.tods_Date

FiscalyearId and FiscalMonthOfYearId are both int.

Can someone please help me with this.

Thanks
