Edit: 132: attempt to call string

I wrote a program for a turtle to craft different tools based on a touchscreen input from a monitor. I ran it after editing a few lines of code, and nothing happened. I then tried to edit it, but I received an error: "Error: 132: attempt to call string". I don't know why it's doing this. I checked my saves file and the program is still in there. What's going on?

More likely than not, you defined a string with the same title as one of ComputerCraft's in-built functions. You likely also made it a global variable, meaning that it's remaining loaded in memory even when your script completes - it'll stay there until you reboot the computer, interfering with any other scripts that relied on the original function pointer.

If you can't figure it out, post your code.

I rebooted the computer and now I can edit the code. I also noticed that I named a variable 'type'. Could this be the problem?

Certainly could be.

I renamed the variable and defined it as local. It fixed the problem. Thanks a billion!
