Hi Paul,
Each editable hotspot should correspond to a single parameter.
As an example of what you're trying to do - adjustable column widths (I think?) - take a look at DET_Detailer_Template 10 in the US library here:
Object Library 10.lcf > 01 Genearl 10 > Detailer Library 10 > Symbols 10
There are two editable hotspots at the top which let you stretch the widths of the dimension and notes columns. (Another editable hotspot at the top right lets you stretch the entire template in integral multiples as described in the Detailer help file.)
The hotspot code is at the bottom of the 2D script (and in the parameter script).
The code there is a little trickier than usual because the object was designed prior to AC 10 for placing on a plan, section or detail window and for stretch feedback to be given in print units, rather than model units. So, there are some fake parameters to allow the user to see feedback in paper-space inches (if you will) vs whatever the current model units might be.
Hope that helps.
Karl
