Welcome. Thank you for using the site.
The usual process is for the customer to post their questions, usually by attaching a Word or PDF file to their post. You can use the "paper clip" button on the toolbar to select and attach such a file. In some cases, it is possible to directly enter the text of the question or problem, but often the formatting becomes an issue, or certain math symbols do not appear correctly. This is why a Word document or screenshot is preferred.
Once you have your question posted, I'll be happy to take a look at it and let you know if I can assist with it, and how long it might take to complete.
After the solution has been posted, you'll have an opportunity to ask follow-up questions if there are parts of the solution that you do not understand.
Once you are satisfied, you are asked to rate the service that you have received. This rating is important as it is the only through this rating that the expert is compensated for their work.
If you would like to proceed, then please post the problem at your convenience.
