autoIncrement block not working within a Python Toolbox?

[DPG]

Hey guys. I am creating a python toolbox that assigns selected polygons in a shapefile a unique id. This id features a section of string followed by a sequential ID. However, whenever I insert the following code block for autoIncrement into my script, the tool will no longer launch. This is the autoincrement block I have taken from ArcGIS Resources:

        rec = 0
def autoIncrement():
 global rec
 pStart = 1 #adjust start value, if req'd 
 pInterval = 1 #adjust interval value, if req'd
 if (rec == 0): 
  rec = pStart 
 else: 
  rec = rec + pInterval 
 return rec

I am placing it in the " def execute(self, parameters, messages):" section of the python toolbox template.

Any ideas as to why this is causing my script to fail? Thank you!

It would be most helpful if you could post the error message, as well as the complete python file. I don't think there is anything wrong with the snippet you posted so there must be something else. Thanks

I'm afraid there is no error message. Where I can usually select the script (seen here as "Tool")...

... After pasting in that code block into the script, the option disappears as shown here:...

If you right click on TestToolbox.pyt do you get an option to "Check Syntax"?

Here's the error:

For context, here's this part of the code:

    def execute(self, parameters, messages):

        # Sequential Formula

        rec = 0
        def autoIncrement():
            global rec
            pStart = 1 #adjust start value, if req'd
            pInterval = 1 #adjust interval value, if req'd
            if (rec == 0):
                rec = pStart
                else:
                    rec = rec + pInterval 
        return rec

Apologies for the lack of clarity. Line 112 is line 12 in my pasted code.

Ah - now I see.  Lines 12  and 13 are indented incorrectly.

Wow, how foolish of me. Thank you! Think I've been staring at code for too long.
