(sos!) Help me fix some problem for my Sorting (name and score)

@ABG

Testing against the latest high score list would require having a copy of the high score list available locally.

but I thought u said use one database is more easier than using 2

@Thomastan_Genius

u said use one database is more easier than using 2

Where?

You keep adding requirements, so more work is needed.
Multiple screens can't talk to each other.
TinyDB is easier than CloudDB for local storage, and you should be able to distinguish between the two and know where to use one and where to use the other.

what if now they are in same screen

[ABG]

All username and score information must be available before attempting to update it.

The screen Initialize event is a good place to ask for the latest high score list.
It should arrive before the user has a chance to enter his name and confirm.

do u have some kind of similar video for this, I'm lost (sorry I being so foolish ). Especially, I never learn the table.

I added a new, simpler, tutorial for CloudDB top scores under a single tag.

Top 5 Scores to CloudDB, Single tag

This is the simplest possible single tag CloudDB sample for a top 5 score list. Sample runs: [first run] [6th Run] Designer: [Designer] Two text boxes are used for entry of player name and score. A button is used to add the score and name to the top 5 list in CloudDB Scores are lined up with Names in two parallel ListViews. (Tweak the widths if you want to get fancy.)

tq i will try now

[Thomastan_Genius]

i should create a independent database for username?

[ABG]

Tell us where "ttttttt" came from.
It is not a list.

[Thomastan_Genius]

now, become this. I think is from the result(name,score)

result:

[ABG]

Use the Companion and the Blocks Editor Do It facility to show the contents of that global scores table.

[Thomastan_Genius]

sorry, can i look the image of the Blocks Editor Do It

[ABG]

Without the Do It facility you are working with one eye tied behind your back.

[SteveJG]

problem is use of the values one of this block (the operation > cannot accept the arguments ...) based on the error message.

You possibly can use DoIt to debug.

Use the MIT debugging advice Live Development, Testing and Debugging

[ABG]

There is a red X in your blocks image, in the gethighscores procedure.

That procedure is incompatible with storing scores and names in a table.

I advise removing that procedure.

You have fallen for the sunk cost fallacy, where you have devoted so much time and money into something that won't work, that you are reluctant to give it up.

I, for one, will not fall for that.

[Thomastan_Genius]

i save as copy and run with other projectId for cludDb, now it turn to this result ( show only 1 value, and keep replace it when it is higher than the existing value)

[Thomastan_Genius]

omg, i just got the 5 result !!!!(is my size of the listview problem i guess hahah)

[Thomastan_Genius]

may i ask how to adjust it to follow the ascending order

[ABG]

There is a reverse list block.
