negative\postitive

[rjhe22]

hi
i want to be able to do this
when the amount coming in is positive if returns a c and if amount is negative it returns a d
this is what i have tried

If SNEX_ARRAY$(EXE_AMOUNT) < 0 Then
 SNEX_ARRAY$(EXE_CD) = "d"
 Else
  SNEX_ARRAY$(EXE_CD) = "C"
  End If

any ideas why it doesnt work
