Vlookup returning 0 instead blank cell

hii guys,

Im facing a problem, i have this formula "=VLOOKUP($F$2;Base!$A$2:$FC$898;139;0)", and i dont want it to return "0" as value, how can i avoid that?

Maybe:
IF(ISBLANK(VLOOKUP($F$2;Base!$A$2:$FC$898;139;0)),"",VLOOKUP($F$2;Base!$A$2:$FC$898;139;0))

It works, many thanks
