Calculate sum of children values automaticaly with [=sum]

Hi,

we are using Calculate sum of children values automaticaly with [=sum] fonctionality, the issue is that whenever we use it the child cell for that column becames non editable, so we can’t put figures on the child cell to calculate the parent’s total.

thank you in advance for helpping us.

try to use

mygrid.enableMathEditing(true);
