I found that in certain situations is more convinient to create and then to delete fields or buttons from vithin the script any time when, for instance, the number of lines, to which you have to show controll buttons are different. It works perfect and easy, but I start to think, how long the programm, which I make, will be used, if any time when user does a certain action, a group of new buttons with new IDs is created? Is there a limitation for the ID number?
I hope, my question is more or less clear for the experts.

Thanks,
