Hi All

I have a gallery with 60 questions (sourced from SharePoint list) and with dropdown for user to select an answer, which is concatenated into JSON string by following action:

UpdateContext({
 S_result: Mid(Concat(QuestionsG.AllItems, "; Q" & ID & ":" & QScore.Selected.Value),3,1000)
});

The problem is that only first 10-15 values actually collected and all following are left blank. I added a label to check the output:

S_result & " 
 " & Mid(Concat(QuestionsG.AllItems, "; Q" & ID & ":" & QScore.Selected.Value),3,1000)

and hear is what I get:

Q1:1; Q2:1; Q3:1; Q4:1; Q5:1; Q6:1; Q7:1; Q8:1; Q9:1; Q10:1; Q11:1; Q12:1; Q13:1; Q14:; Q15:; Q16:; Q17:; Q18:; Q19:; Q20:; Q21:; Q22:; Q23:; Q24:; Q25:; Q26:; Q27:; Q28:; Q29:; Q30:; Q31:; Q32:; Q33:; Q34:; Q35:; Q36:; Q37:; Q38:; Q39:; Q40:; Q41:; Q42:; Q43:; Q44:; Q45:; Q46:; Q47:; Q48:; Q49:; Q50:; Q51:; Q52:; Q53:; Q54:; Q55:; Q56:; Q57: 
 Q1:1; Q2:1; Q3:1; Q4:1; Q5:1; Q6:1; Q7:1; Q8:1; Q9:1; Q10:1; Q11:1; Q12:1; Q13:1; Q14:; Q15:; Q16:; Q17:; Q18:; Q19:; Q20:; Q21:; Q22:; Q23:; Q24:; Q25:; Q26:; Q27:; Q28:; Q29:; Q30:; Q31:; Q32:; Q33:; Q34:; Q35:; Q36:; Q37:; Q38:; Q39:; Q40:; Q41:; Q42:; Q43:; Q44:; Q45:; Q46:; Q47:; Q48:; Q49:; Q50:; Q51:; Q52:; Q53:; Q54:; Q55:; Q56:; Q57:

Number of items with set values and blank values is always different, but usually set values are first 10-20 items.

Any ideas what could bee wrong?

Thanks
