Inputsum update the wrong line

[Anonymous]

Hello,

I'm trying to use the inputsum function.

I have added on my script the line 'inputfield':

INPUTFIELD WEIGHT;

And into a tab, i have created a expression:

inputsum(WEIGHT)

Now, I can update values of my table.

The issue is that the line updated is the one above.

Exemple: I have the table:

Event1     30

Event2     20

Event3     10

Event4     5

If I tried to update the line Event3, but it is the value of the Event2 which is updated.

Is anybody has already had this problem?

Thank you
