How I can post varitables between forms??

You might consider inserting all your variables into a container and then using the parmObject function of Args class to pass them.

Also, you might create the methods returning the needed variables, or, again, just one method returning a container on one form, and call this method in the other (but you need to know the args.caller() to be your first form)

About using ARGS you can read in the developer's guide, or follow this link:
