Subscript used on non-accessible variable

3 posts in this topic

Hi Guys,

This forum has been helpful and some problems have been solved through looking at various solutions on this site. I am having problem with this code below and I have tried to look at the code and it was working initially and then stop working. Please any way to solve this and make it work without coming with this error. The error is  ==> Subscript used on non-accessible variable.:
$SER1 = StringTrimLeft($test[0], 1 )
$SER1 = StringTrimLeft($test^ ERROR

The program is searching through a file and then extract the first five digit of the filename and also go into one of the file in the folder and then search .vhd and look at a serial number of a particular AC.

 

Please looking forward to any ideas.

Code is

#NoTrayIcon

great77,

Welcome to the AutoIt forums.

The reason you are getting the error is that at some point your RegEx is not returning any matches from a line of the file - so there is no $test array to access. So I suggest you add some errorchecking in your code to cater for this event - then the error will not occur.
