I have searched high and low for an answer to this (including two previous posts), so PLEASE help if you can.  Here is the situation:  I would like to modify several master shapes by adding custom properties that the user is prompted to enter when the shape is dropped on a drawing.  Also, I want the property values to automatically display under the shape when it is dropped.  This sounds simple enough, however, when I attempt to edit the master and insert the fields in the attached text box, the custom properties are (sometimes) not available!  When I can get the custom properties to display on the drawing, for some reason it does not prompt for values.  Any help would be greatly appreciated.

To edit and show Custom Properties on my drawings I right-click on the shape (ie HP 2524 switch) and select "shape" from the drop-down menu, then select "custom Propertise" from the secondary drop-down menu.  If there aren't custom propertise available it asks if you'd like to create them.  Hope this helps.

1) Create new master.
2) Add to master text block.
3) Group 2 shapes
4) Add Custom Properties to group.
5) Edit text fields in text block of group(CustomFormula=Sheet.ID!Prop.Row_N).
6) Set in ShapeSheet of group in Events section, EventDrop Cell =DOCMD(1312)
And when master is drop on drawing it will show Custom Properties window and it's values will be under the shape(with it's names if you want).
