I am hoping someone can help me....

I am currently building out a spreadsheet and have successfully (I hope!) used this formula
=VLOOKUP(MROUND($D$13,2),Sheet2!$A$1:$H$353,2,TRUE ). It's returning the numbers that I need. What I would like though is for it to return a 0 instead of N/A when the information is not available. I am using the results in calculations and really need it to return either a 0 or be blank.

Thank you for your help!
