Hi there,
Troubleshooting issues just like the issue that you have described is one of my favorite things to do and I would love the opportunity to take a quick look at the file to determine the best way to ensure that the formatting remains in tact each time you open the file.
I have over 17 years of corporate experience working in Excel creating advanced automated dashboards, reports and calculators which included beautiful graphical displays of data/information. I think given my experience I would be a great fit to assist with the issue with your file.
I now operate my own Excel based home business 100% full time using the skills I've obtained throughout my corporate career. I have a few portfolio items on my Freelancer home profile if you want to take a look, and I have a more detailed file with numerous screen shots of my work as well – I can send it over for your review if you’d like.
Hopefully I can hear more and take a look at the file and we can work together!
Thanks either way for reading my proposal and best of luck,
Shaun
