Although the Mtl.hypertext script is flexible in allowing creation of search sequences, it is not yet independently portable to other stacks. Its proper function requires the presence of other elements in the stack. You cannot simply copy and paste the "hypertext" button to another stack and expect it to work - in the present version.
A simple way of moving Mtl.Hypertext to another stack is to save a copy of the original stack, then rename it and then modify. Be sure to change the first line of the first card's field which identifies the path to the stack. Note that since it is a text field, you can use the usual cut and paste functions. You may need to "Bring Closer" the field and button to allow them to be seen when shown: they should be above any other card fields or buttons. Be sure the first card remains such.
Basically, any stack with a pasted Mtl.Hypertext 2.0 button will require in the first card: a card field named "Mtl.Hypertext search heirarchy" to store the search sequence; and a card button named "Mtl.Hypertext Heirarchy Ordered", with script. These can be copied from the original stack when they are shown initially - before clicking on the "Mtl.Hypertext Heirarchy Ordered" button which hides them. Again, be careful that the card they are pasted on remains the first card, and that the first line of the card field is the path to that stack.
Optionally, the script for this stack can be retyped into that of the new stack, to allow for the option of changing the search hierarchy after exiting the stack rather than only after exiting HyperCard. If you prefer the latter, simply delete the command:
