The function "getElementData()" returns false if the requested data doesn't exist. Maybe is it.

[FSXTim]

No Error now, thanks!

But still having a problem:

I bought a 'Repair' but there is still '0' in the database @ 'Repair'!

Does anybody has an idea?

[FSXTim]

No idea ?

[Stanley Sathler]

I don't know much about "setElementData()" and "getElementData()", but maybe you should use setElementData() to store "1" (or other value), no?

Example:

setElementData(lp, "Repair", 1) 

I should be wrong, but I'm trying help.

[FSXTim]

Yea, thanks for your answer!

But I have to tell you this is wrong, because what is, when the player buys 2 Repair items? Then the script set it alsways to '1', but the player bought 2 items, you know?

[Stanley Sathler]

Oh yes, I understood. So I'm sorry, I can't help you. ): Maybe in another time.

[FSXTim]

But thanks!

I'm not sure if this is solved but,

Did you set the element data before?

If you didn't, then i suggest setting it before trying that line of code(line 7)

Thanks for your answer. I didn't set the element before. Maybe you can have a look here:

I suggest you to use MySQL instead and insert each item in the table.

[FSXTim]

I suggest you to use MySQL instead and insert each item in the table.

Thanks for your answer, but what do you exactly mean?

Greets

[Anderl]

You should use MySQL database system and create a table for bought items and when a player buys a item, insert player name, item bought, ...

And when you want to get all bought items just search in the table all rows where player name is the name you want.

Understand?

[FSXTim]

I already have a table with all the items ...
