Hi @TANMOY025,
Try zipping the file, I think you can upload zips to the forum.
Thanks for the screenshot. I can see that you have overset text. So you have to shrink the text, not enlarge it! You have to make the text smaller so it fits.
Therefore, try choosing one of the other 2 options ("Shrink or enlarge", or "Only shrink").
That should work!
