When I run my program, it give me an error on line #58, bad argument : number expected, got string, I have no idea why. Can you?
Code: https://github.com/n...ster/rtos/rtgui

no one is going to github just to look at your program. give what wrong, where you think what wrong. dont just send everyone your whole program in github

I sent the exact program with the error, and I said the error.

It doesn't matter where he sends us, as long as the code is visible. He also stated the error and the line. Please read before posting.

I just went there; your statement is invalid

btw, best to put your menu in a table, and use a print table function, like this for your menu

[size=4]Menu = {
[size=4]"X------X",
[size=4]"X		X",
[size=4]"X------X"
}

[size=4]function printTable(table)

for i=1, #table do
print(table[i])
end
end
printTable(Menu)

UNTESTED; SHOULD WORK
small version of menu
NOTE: ignore the [size=whatever]

Not a fan of using arrays to read the contents of a table. Also that would not work since you are overriding the table api with a table named 'table'.

for k,v in pairs(menu) do
 print(v)
end

This is also off topic. You are avoiding the error at hand and simply went off and are now lecturing him about how he should make his program. Let's focus on the problem.

Well, the error is that you got the arguments for string.rep backwards, the string should be the first argument and the number the second.

Actually, iterating using a counter (like for i = 1, #tbl do) is faster than using pairs (it's too small to notice, but for larger tables - really larger tables - you may notice it). Also, pairs doesn't ensure that the table will be iterated in order, so it would be better to use ipairs.

[SuicidalSTDz]

I guess since ipairs returns three values (an iterator function, the table, and 0), it would be the superior choice, now wouldn't it. I always take ipairs for granted I still don't like using an array to iterate over the table. But meh, that's just me

Wow, I was editing a copy of this program when I fixed that thanks
