I have XI.
My report has a detail line, which contains a description (text) and an inserted box.
I wish to suppress the line if this description is blank.
I have gone to Section Expert and coded against
Suppress ( No drilldown)

if isnull({Description}) then
    true
else if {Description} = ' ' then
    true
else
    false

However, I still get lots of rows, with only boxes in them.

And there is nothing in Format Box, to suppress the box depending on other fields,

Can anyone help me please ?

Thanks Savan
Do you mean in the Suppress (Drop Down) ?
I changed the code in there to :-
If ltrim(rtrim({Description})) = "" then
    true
else
    false

But still get the blank line with the box !!

Thanks for your ongoing help Savan.

The detail line has a description and the box.
If there is a description, I want to see it and the box.
ie   the line should not be suppressed.

But if there is no description ( null or spaces), then I want to suppress the complete line.

At the moment, I am getting lines with no description, but with the box printed.

thanks to Savan & Sarah
Report fine now.
