Nested if statements with vlookups

I am trying to write a function where if vlookup returns 0 or is NA then the cell is "blank" otherwise it ruturns the value of the vlookup. The function is working in that if it is 0 it is returning blank but if it is NA it si giving me a #NA. How come the second half this function is not working properly.

=IF(VLOOKUP($B12,Data!$A$7:$G$264,7,FALSE)=0,"",IF(ISNA(VLOOKUP($B12,Data!$A$7:$G$264,7,FALSE)),"",VLOOKUP(B12,Data!$A$7:$G$264,7,FALSE)))

Thank you in advance for any help you can give. If you know a better way I am open to other ways to write this.
