help with this error please

I am using someone else's script. When i try rtunning this script(autominer)

i keep getting this error when running :

Code:

Line 349: [Error] (349:4): Unknown identifier 'IsTextAt2' in script C:\Documents and Settings\LocalService\My Documents\Script Based Cheats\SCAR + SCRIPTS\Older Scripts\OSi.txt

 

Find a new script, that one won't work because it's extremely old.
