line edit data input

**BrianBrian** · 6th May 2015, 01:48

Hi, i would love a little direction here please as i have been searching but not finding a solution to my issue.
What i would love is to take the data i enter into the line edit field of my gui and send that data to a string in my list. In the case below it is the value at ls[0] that i want to change to the value i enter in the gui line edit field. (not using line edit_2 at the moment) Am i going about it the wrong way?
