I apologise in advance but I have resorted to posting all of my code as I'm really struggling on this!

I have created a table which is initially empty then a user imports a text file and creates 'n' rows depending on the content. Each row has an option menu which creates an additional set of boxes for that row (or should do).

In the following I need to finish doing these few tasks:

  1. For the choice 'Fixed' I need to delete anything create by the other options 'List' Etc. I am however being left with a black box and a grey header. Why doesn't the grid forget what I want it to?

  2. I cannot get the correct row number for each OptionMenu. When I import a file, it creates new rows but I need to then know which OptionMenu (i.e. which row has been clicked on) to create the 'List' or 'Min/Max' boxes next to that particular row. I am currently only getting the final row created. This may be the same problem upon deleting these boxes but for the correct row.

  3. I need to obtain the values entered by the user in these additional boxes but with the 'List' option, there could be 'n' boxes and therefore need to return 'n' values but am having serious problems with lambda errors where it only accepts a certain number of arguments..

If any other explanation is needed or any advice in general could be given I would hugely appreciate it!

Thank you in advance!

Can not make much of your code, except that after fixing numerous indention error and putting one pass to def without statements. I got it run and after giving it one random text data file as input, it complained of KeyError. Why is three defined again for each iteration of loop at line 243?
