Bobiman,

THe only way I know how to do this is to use shared variables. In the main report create a formula field as:

shared stringvar test1:='';

You can use different declarations for different variable types.

In the subreport create a formula field as:

shared stringvar test1:= value where value is the field you want to pass back.

In the new report create a different formula field as:

shared stringvar test1;

Variables became available in version 7.

Prior to version 7 you could use Fetch and Store functions. They were slow but did the job okay. Editor and Publisher of Crystal Clear

You can use the same idea, but of course you can not use the parameter as a filter in the main report. WHat you could also do is create the parameters in the main report and use them in the linking of the subreport.

When doing this you should scroll down to the parameter name in the subreport and not use the default {?pm...} parameter. There should be scroll arrows but these are not very clear.
