Dik za snahu...nakonec byl problem v tom, ze jsem se spolehnul na navody 
co jsou ruzne po internetu, kde nechapu proc neni nikde korektne 
sestavena hlavicka dotazu... Nakonec jsem se na to vybodnul a sestavil 
ji jak jsem zvyklej a okamzite se data prenesla.

No tak ted uz snad jen sama pozitiva a svetle zitrky.

Dik.
