Thank You. I think the second parameter of the instruction
Dynamic [p1 (p1 = #; MiFp [#]) &]
is not working in CDF. It's a shame, because it provides a good window for better programming. For my purposes Manipulate seems limited.
I'll wait to see if this alleged error is corrected in the future. If so is the case.
I attach a new version without MessageDialog. Which of course does not work in CDF.
Best regards
