Grid summary plugin: problem with summaryType: sum

[shadow_m]

Hi!
I have a problem with Grid Summary plugin.

My grid has 3 columns: 1) count 2) price 3) Sum

Sum column has a renderer:

{
 xtype: 'gridcolumn',
 dataIndex: 'cost',
 text: 'Сума',
 renderer: function(v, params, record)  { 
 return '<span style="color:blue;"> '+ record.data.price * record.data.count + ' </span>';
 }
},

I am trying to use summaryType: 'sum', but it show "0" instead of real value.
How can I fix it?
Thanks

Najbolje da napravis custom funkciju summaryType: function(){} pa da ona uradi sumiranje

Can anybody help me with this?

try using custom summary function

summaryType: function(){....}

see in docs about params or use console.log(arguments) to find params that function uses
u can make custom summaryRenderer function also, see docs
