Why am I getting this error?
This works
This give me the error on line 123. As far as I can tell there’s no difference between the two.
Do a find/replace in your text editor: find all tabs and replace w/ 4 spaces OR find all 4 spaces and replace w/ tabs.
Python can take 4 spaces to indent or a tab, but not both. Pick one and stick with it 
Finally, it looks like the code under the if statements is indented w/ only 2 spaces: these should be indented with 4 if you are going with spaces, or one tab if you are going with tabs.
BTW it is quite a debate about which to go with so please don’t ask a question like that, but if you want my opinion USE SPACES
in bl text editor there is an option to convert space and tab
happy bl
Got it working, that seemed to be the issue. The one that worked had 4 spaces on that line and the one that didn’t seemed to have a tab. Python is definitely foreign to me so the little things are confusing, LOL.
