Yes, the catch was I didn't make my variables as public, but it have to be, because after the Load() they were gone. In FP 2.6 I declare my variables in Setup event of the Screen and they are there all the time until the screen is closed.

Thank's, it works now. I only have to keep in mind that I release this variables in the Unload().
