hi guys,
im using 2K5 and im in quite a pickle here. hope someone can help me out.

what i want to do is when the user inputs the letter "g" my program will check if the preceding index is an "n" and if it is both the letters "n" and "g" would be replaced with the symbol "]" as i type

provided below is the code i curently have.

but my problem with this code is when you input "g" it will swap out "n" & "g" for "]" and it will keep doing this everytimei "g" is pressed and while  there is an "n". and as a result it will swap out "n" characters that i don't want to be swapped out.

all i want is whenever i type "g" the prog. will check the preceding index if its an "n" and if yes it will swap "n" and "g" with "]" thats it.
