I have a report that is group sorted by CostType. These are 1,2,3,4... and are ascending through the report.

I have been asked to sum costtype 1 and 7
So far I removed 7 from showing by adding

{JCCT.CostType} <> 7

Now I want cost type 1 to include costtype 7.. something like this.

//if {JCCT.CostType} = 1 then sum ({JCCT.CostType} = "1" ,{JCCT.CostType} = "7")

Any ideas?  I have no programming background so I am stumped.

Thanks for trying...
I get "a boolean is required here"
 I am just trying to add 2 rows together.
I have a report that prints

cost type   estimate  actual    balance

1 labor        100         100          0
2 materials   200        100       100
7 burden      500         600      -100
10 tax           0             0           0

They want me to combine the labor and burden

Ah! Thank you ,getting the right stuff now.
looks like you can teach a old dog new tricks.

Thanks,
