#Unabable to update values in SIte level

Question

Hello all, I am currently working on an interface that includes an editable grid. Although the backend processes the percentage field modifications correctly, the site displays incorrect values, particularly in some other rows.

I'd the problem lies in the way you are doing the update with the indexes. Here's an example of what I think you are trying to achieve. 
 a!localVariables(
 local!records: {
 a!map(percentage: 1),
 a!map(percentage: 1),
 a!map(percentage: 1)
 },
 local!indexesToUpdate,
 local!caseSubmit,
 {
 a!gridLayout(
 headerCells: { a!gridLayoutHeaderCell(label: "%") },
 rows: a!forEach(
 items: local!records,
 expression: a!gridRowLayout(
 contents: {
 a!textField(
 value: fv!item.percentage,
 saveInto: {
 fv!item.percentage,
 a!save(
 local!indexesToUpdate,
 append(local!indexesToUpdate, fv!index)
 )
 }
 )
 }
 )
 )
 ),
 a!buttonArrayLayout(
 buttons: a!buttonWidget(
 label: "Submit",
 saveInto: {
 a!save(
 local!caseSubmit,
 a!localVariables(
 local!casesToUpdate: index(
 local!records,
 local!indexesToUpdate,
 null
 ),
 a!update(
 local!casesToUpdate,
 { "createdOn", "createdBy" },
 { now(), loggedInUser() }
 )
 )
 ),
 a!save(local!indexesToUpdate, null)
 }
 )
 )
 }
)
