Hi,

I am getting Index Warning in powerapps form, where I have used collection to retrieve the value using Index function .

Index(CollectItems,1).Title 
 
And I cleared the collection after the submission, again I replaced the value with the last record submitted. I checked the collection which is not empty. But still I am getting this Index Warning attached.

One way to avoid this is by checking if the collection has any data before using the Index function. You can do something like If(CountRows(CollectItems) > 0, Index(CollectItems,1).Title, "No Data Available") to make sure it's not empty when accessed.

Alternatively, using First(CollectItems).Title or Last(CollectItems).Title might work better depending on what you're trying to retrieve.

Also, if you're clearing the collection and refilling it right after submission, there might be a slight timing issue. Try adding a delay or ensuring the new record is properly inserted before accessing it again.

I tried using timer , still I am getting index warning once after submit.

I used the below code,

Timer Properties I used: Timer1.Duration = 5000; Timer1.AutoStart = false; Timer1.OnTimerEnd = Clear(Collection); // Patch function to update or create records After Patch,I Set Timer1.Start() and removed Clear(Collection)

Timer Properties I used: Timer1.Duration = 5000; Timer1.AutoStart = false; Timer1.OnTimerEnd = Clear(Collection);

UpdateContext({StartTimer: false});

Patch, I set

Timer2.Start = StartTimer;
