Error in script 690011f5 This would be your editor ID in the CS, it tells you which scriptOperator := failed to evaluate to a valid result
File: kuerteeHorseCommands.esp Offset: 0x000016A9 This is the hex offset in the esp file - useless unless you want to hex edit your esp directly Command: Let (0x1765)
So.. no. Best you get is the script that caused the error (the Editor ID). That last part "Command: Let" may be a reference to the line of code, but most likely it's a reference to a particular engine command. An OBSE editor would know more about that than I would. Your best bet is to check that script line by line - and hopefully it's a short one.
:edit:
the 2nd line "Operator: = failed to evaulate to a valid result" may help you pinpoint the bad line, this looks like it indicates you've got a poorly written comparison.
