Excel

Sounds simple enough to do - but two problems.

1) I think we need to see an example file otherwise we are not 100% sure what you mean.
click on the go advanced button and scroll down to the manage attachments link - then upload the file in that screen.

2) The title of your post breaches our rules.
It needs to be descriptive of what you want distinguishing this post from others. Eg something like "calculate discount applicable based on two conditions".
Since everything in this part of the forum is Excel - a title like "Excel" is really pretty close to the worst title possible...

Your post does not comply with Rule 1 of our Forum RULES. Your post title should accurately and concisely describe your problem, not your anticipated solution.

Use terms appropriate to a Google search. Poor thread titles, like Please Help, Urgent, Need Help, Formula Problem, Code Problem, and Need Advice will be addressed according to the OP's experience in the forum: If you have less than 10 posts, expect (and respond to) a request to change your thread title. If you have 10 or more posts, expect your post to be locked, so you can start a new thread with an appropriate title.

To change a Title go to your first post, click EDIT then Go Advanced and change your title, if 2 days have passed ask a moderator to do it for you.

(This thread should receive no further responses until this moderation request is fulfilled, as per Forum Rule 7)
