Dear Shivanagar,
I appreciate you so much sir!! You know what, I have been spending so many hours searching if this function is available on the Internet. As a matter of fact I took a computer course which taught me all but not this. How did you generate that text for macros? Next time if I want them to make all red or anything how can I do that? If you have any useful website please write that down for me. I really appreciate your work. Another thing is that why did they make it so complex? I think they should make one button which helps "lock" the format and let us type only in bold or italic on that document. Don't tell me lazy again. This is just my thought.

Maxpayne, thanks bro! It was so funny that you told me to send the file and you will do that for me. Don't get me wrong guys, I am not getting lazy but I want to explore things. Earlier I didn't know that a general guy like me could create fillable form in word. I thought only programmers and computer pros could do that. But now by looking at videos I can even make fillable forms.

Thanks again for replying guys.
Have a good night!
