Show link for adding new value

Show link for adding new value

I am creating a class registration database for a nonprofit, and Zoho looks very promising.  I have run into one stumbling block.

When creating a field of type "import data" you get a drop down interface showing all the values of a specified field in another table.  You also get an option to "Show link for adding new value"  Is there a way of getting the "link for adding new value" without creating a dropdown list?

I have a class registration database that contains a "parents" table and a "students class registration" table.  In the "students class registration" form I ask the user to enter the "Parent's Account Number" in order to create a many-to-one relationship between "students class registration" and "parents."  This is now working as intended with the dropdown, however I want to put the  "students class registration" form on our website, and therefore I want to eliminate the dropdown that would publicly expose all of the parent account numbers.  Instead I would like to use a field of type "single line" to enter the "Parent's Account Number"  I use an "on validate script" to direct the user to click the "link for adding new value" if the "Parent Account Number" that is enterd does not exist.

I can use a "dummy" drop down to make the link appear on the page, but then it is not placed next to the field where I want it.

This is a long explanation,, I hope I have been clear.
