Problem looping and switching between sprites - deadaimsave - Jan 8, 2014

Basically I have two images of a character to make it look like it's walking. I simply want him to walk across the screen.

My code uses the Corona SDK and since some of you might not be familiar with that, I'll just simplify it:

Code 
for i = 0, 150, 2

   if sprite = 1 then

  move sprite over by current position + i

  sprite = 2

  pause for 500 miliseconds()

   end

   if sprite = 2 then

  move sprite over by current position + i

  sprite = 1

  pause for 500 miliseconds()

   end

end

When I run it, the character instantly moves to the ending position, only 1 frame change is noticeable, and all the "pauses" happen AFTER the loop is finished (when I debug, the loop starts, both the if statements are executed, and then it loops 74 more times without any if statements being executed. Then after looping is complete, it executes 2 pauses.)

I have no idea why this would happen and would appreciate any suggestions. Thanks!
