Error: Subscript used on non-accessible variable

[lucas9]

Hi everyone

I have this function to convert some data:

func ConversionDatosCapturados($in)
    Global $tmp_filename = "tmp_" & GenerateName("cccccccccccccccccc") & ".jg"
    FileWrite($tmp_filename,$in[0]) 
    Global $in_convert = FileRead($tmp_filename)
    FileDelete($tmp_filename)
    Return $in_convert
EndFunc

This funcion is running in one of my computers without any error, this week i have copied all the script to a new computer and i have got this error:

Quote

Line 5 (File "C:\xxx)

FileWrite($tmp_filename,$in[0])

FileWrite($tmp_filename,$in^ERROR

Error: Subscript used on non-accessible variable.

if i remove the "[0]" error dissapears but this "[0]" makes the data conversion.

Someone knows any solution?

Thanks in advance.

Check that the variable $in passed actually is an array. In your problem-case, it clearly isn't.

thanks.

i can not understand your reply. why you say that $in is not an array?

Because of the error message! You aren't passing an array to the function, at least not in the case where the error pops up. It generally comes from a previous unchecked error in the calling code.

Then you shouldn't declare global variables inside a function.

Also may I ask what's the intent of the function?

You can tell the $in is not an array in this case because the error specifically says so. Whatever you're passing in as the argument for that method is apparently not an array.

If you're passing in something that is supposed to be an array and it works on another computer, then there's a difference between what happens on both computers. Whatever is used as the argument for that function call is somehow an array on one computer but not on the other one. However, there are myriads of conceivable causes for that; so for more help, please show how you call the function and how your script decides what goes in as an argument. (Totally random example, first thing that comes to my mind: say you StringSplit a filename from some hardcoded diractory and feed the result to this function... If the directory exists on one computer but not on another computer you would get this problem.)
