This my php file:

include_once('tbs/tbs_us/tbs_class.php');
include_once('tbs/tbs_plugin_opentbs/tbs_plugin_opentbs.php');
include_once('tbs/tbs_plugin_aggregate/tbs_plugin_aggregate.php');

$TBS = new clsTinyButStrong;
$TBS->Plugin(TBS_INSTALL, OPENTBS_PLUGIN);

In docx I am using this:

[a1;block=begin]
[a1.Num] [a1.Art;block:tbs:row;aggregate=Total:sum]
[a1.Total:sum]
[a1;block=end]

And I am getting the following error:
TinyButStrong Error in field [a1.Total:sum...]: item 'Total:sum' is not an existing key in the array. This message can be cancelled using parameter 'noerr'.

Hello
The following code solved my problem. It was the formating issue with template:


[sub.Num;block=tbs:row;p1=[main.PId]; aggregate=Total:sum]    [sub.Art;]    [sub.Menge]    [sub.Ansatz]    [sub.Total]
       
Total:        [sub.Total:sum]

Thanks
