Extract Previous Cell Value

I have a cell with char values next to each other as seen below
Cell 1 | Cell 2
____________
'Hello' | 'World'
I would like to define a function that extracts the previous cell value along with the current cell value. I wrote the following code to do so:
t = x{1,i} - Current Cell Value
f = x{2,i-1} - Previous Cell Value, starting with Cell 2 with the previous value of Cell 1
But I keep getting the error
Index in position 2 is invalid. Array indices must be positive integers or logical values.
I believe the error is with regards to the defined function f. It has to do with the i-1 value. At this point, I am stuck. Any thoughts on how to fix that so it works?
