Chaim,
the best way to do this is to use the (print when) setting in the field. You need to duplicate the field for each font you want to use. I just take the 1st field do a copy and paste for each font I need. Then in each field under Print When enter the condition you desire in the bottom box Print Only When Expression Is True. You then have to take all the fields and stack them overtop of each other. Each one must be set to only print on a unique condition. I have used this for up to 4 fields but it should work on even more. Just don't try to print it on a dot matrix printer.

>What can I do if I have few condition (if valueis 'S' - font bold=.t., if 'E' - font italic=.t., if 'D' -fontsize=9, if 'R' - fontsize=12 and fontbold=.t. etc..)?
>I have to build dosen copies and each one in the 'print when' to fill conditions for all the other?
