Single Multi Column text frame to individual separate text frames - Nearly working - Please help

Hello All, 

I have the bulk of a script which takes a single frame of which has multi columns to split each of the columns into spearate, but threaded boxes retaining the same gutter etc

the only issue that the script repeats the text an eqaual amount of times as there are columns 

as the script duplicates the single frame the same amount of times as there are columns and also then once done drops the text frame to only have one column.

Below is the code

Also this can be undone in one go to which I saw another online which was much longer code and couldnt be undone in one go

Any help or advice would be great

Best
