Hi,

I have a gallery which contains questions and answers. Each question set is identified by TestIdentifier. E.g if i have a question set of 20 questions then its testidentifier will be same. I am putting all questions in collection . then I am iterating Collection & updating corresponding record in db using patch and lookup. This code is not giving error & also not doing anything. Below is the code & urgent help will be appreciated.

Clear(QuestCollect);

Collect(
QuestCollect,
ForAll(
Gallery_1.AllItems,
{
Answer: txtAnswer.Text,
QuestionID: lblQuestionID.Text,
TestIdentifier: lblTestIdentifier.Text,
Comments: txtComments_ExternalCor.Text
}
)
);

ForAll(
QuestCollect,
Patch(
'Test QuestionSet',
LookUp(
'Test QuestionSet',
QuestionID = QuestCollect[@QuestionID] && TestIdentifier = QuestCollect[@TestIdentifier]
),
{Answer: QuestCollect[@Answer]},
{Comments: QuestCollect[@Comments]}
)
);

Hi @Anonymous ,
I cannot see your data structure, but I have coded the below as I would from a collection with plain Text values.
You might try this.
ClearCollect( QuestCollect, ForAll( Gallery_1.AllItems, { Answer: txtAnswer.Text, QuestionID: lblQuestionID.Text, TestIdentifier: lblTestIdentifier.Text, Comments: txtComments_ExternalCor.Text } ) ); ForAll( QuestCollect, Patch( 'Test QuestionSet', LookUp( 'Test QuestionSet', QuestionID = QuestCollect.QuestionID && TestIdentifier = QuestCollect.TestIdentifier ), { Answer: QuestCollect.Answer, Comments: QuestCollect.Comments } ) )

Here its giving error at (=)
QuestionID = QuestCollect.QuestionID
I think @ is the proper syntax to get value from a collection field. My code runs without syntax error but it comes out from loop very quickly. I think its not executing the complete for each loop. I have already validated collection, It contains proper records.

OK @Anonymous ,
This may be something in Regional syntax as .xxx works for me - you need to put them back.
Without seeing your code, there are two things I would initially test.
Have a look at the Collection QuestCollect and see if they are the records you were expecting.
Look at the fields in this QuestionID and TestIdentifier and ensure they match the relevant fields in 'Test QuestionSet'
