For some other issues I have to use the "ID" to link one subform to another. Which is fine because in forms you can use the "Display as" advance option to display the field as a Drawing number or whatever else it may be.

The problem is that in a HTML file it is displaying the ID as a long number - how do I script it so that the Drawing number (or whatever else I may be using) is displayed rather than a long, unrelated number?

Many thanks
