Nulls and zero-length strings in Add/Copy Page

I have a field on my SQL table which is set to a value calculated by a SQL function if a record is inserted with a null value.
In ASPRunner:

  • if I Add a new record, I want this field to be passed as null so that the SQL function triggers.

    -if I Copy a record, I want the value in the existing record to be passed into the new (copied) record.
    The problem I have is that the same page handles both Add and Copy, the only difference being that it populates the fields with the values rom the record being copied. If I include the field in the Add/Copy page, I get an error when Adding a record because the value passed is "" and not null.
    Is there any way round this?

I guess you can use BeforeAdd event and the following code:

if dict("FieldName")="" then dict("FieldName")=NULL

I tried that, but get the following error.

Having investigated this further, I have found a work around by using SQL triggers rather than default values.
