I have two strings, sring1 has preset value and string2 value has to be typed in to check if its the same as string1's value.

When I type in the correct value for string2 and door unlocks, value(numbers typed in) stay on screen.

What code do I need to reset string2's inputted value to none, so it don't show on screen?
