    Posted: 05 Jul 2009 at 4:58pm
I have the following :
-------------------------------------------------
GH1 - {Client}
GH2 - {Batch No}
GH3 - {Sample No}
GH4 - {Test}
      {TestName} (eg Weight)
             Detail a  {Value}  
 
GF4
GH4
      {TestName}    (eg Area)
          Detail a   {Value}
GF4
GH4
       {TestName}   (eg Conc)   
           Detail a    {Value}
 
GF4
GF3  
GF2
GF1
------------------------------------------------------------
I need to calculate, per Sample No (GF3),  the (Weight * Area)/Conc
I am not well versed in the use of variables and this would probably be the way to do it.
After making that calculation I need to use the results to average over the Batch No then the Client etc.
I am using Crystal vs 9
Thanks for any assistance

gh3:
shared numbervar weight:=0;
shared numbervar conc:=0;
shared numbervar area:=0;
 
detail a
shared numbervar weight;
shared numbervar conc;
shared numbervar area;
if {Testname} = "Weight" then
 weight := weight + {Value};
...
 
gf3
shared numbervar weight;
shared numbervar conc;
shared numbervar area;
(weight*area)/conc
 
should do it, not too bad/hard.

Thanks for that.  It is my first attempt at using variables - so I should be able to build and learn from this

Thanks again.
