OK, now if you Evaluate the Name part of a CFParam, then it'll use the
contents of that field as the variable name, so;
<CFParam Name="form.unit#i#_listed" Default="0">
Will set form.unit1_listed to 0 if it doesn't exist, while;
<CFParam Name="#Evaluate('form.unit#i#_listed')#" Default="0">
Will set the value in the field form.unit1_listed to 0, i.e.
form.unit1_listed="myValue", then myValue would be equal to 0
If you want to ensure that the fields (as listed) appear, then use the first
one.
