I have a DTML Document which is based on data obtained from an ZSQL Method. The ZSQL Method has a number of parameters which can be passed from the DTML Document to the ZSQL Mehtod via the following

This works fine for static values. However, I would like the user to be able to specify parameters dynamically by either entering or selecting values on a DTML Document. How could I go about passing parameters from a DTML Document (the one in which the user selects or enters values) to the DTML Document based on the ZSQL Method which then passes those values as parameters to the ZSQL Method.
