Dear Protocomm,

Your code worked, but for more than 8 lines the desired output fails.

Desired output:

Check for form
check above and below  fill word
if above and below fill found, then it is category2.
If only one filll either above or belo, then category1.

Dear Vgersh,

Thanks for your reply.

In the above script category is in increasing order. But in desired output catergory is total 2 only. it have to be printed according to the condition stated:

use form as reference and check below and above fill word, if only one fill found then it should go to category1 and if two fill found then it will be category2.

Thanks in advance,
