How do I make a calculated field default to zero if the answer is negative

[#1]

I have a field that is a calculated field.  Currently my formula (formCalc) for the field "Need" is just $ = Budget - EFC.  This works fine until the EFC field is higher than the Budget, in which case I get a negative number.  I would like for "Need" to be zero if the calculation results in a negative number.  I am pretty new at this.  Can anyone help me?

Thank you

how about something like this?

if(need.rawValue<0)then

need.value="0"

endif

[#3]

Do I leave the original formula as well?

Try this:

if (Budget - EFC < 0) then

    Need = 0

else

    Need = Budget - EFC

endif

I get a script failed:

Error: accessor 'Need' is unknown.

Sorry,  I figured out the problem.  Thank you!  The formula worked just great!  I appreciate your help.

It is formCalc and be sure the field names match the script names.  (no "" around Need)
