What is that?
You write
But I have some asignment like this (t573_l1_c3=0,t573_l1_c4=0,t573_l1_c5=0,t573_l1_c6=0,t573_l1_c7=0,
t573_l2_c3=0,t573_l2_c4=0,t573_l2_c5=0,t573_l2_c6=0,t573_l2_c7=0) for all question.
and your first screenshot shows a validation equation with wrong syntax
1. You shouldn't use "subquestion validation", but "question validation"
2. Here there are a lot of comma separated assignments, but no validation.
A validation is a comparison like "Is the value equal X", OR value==X.
Remember "0" is the assignment operator to set something, "==" is the comparison operator.

If it is equal the validation is TRUE else FALSE and you cannot proceed to the next question.
And, please read the manual about ExpressionScript.
