I've made a calculator which calculates gross and net value depending on tax. Something like this:
Gross | Tax | Net
--------------------------
100 | 10% | is calculated when gross and tax value is inserted
is calculated when net and tax value is inserted | 10% | 100
So depending on gross/net value inserted and the tax, net/gross value is calculated. This is an excel spreadsheet which will be uploaded in SkyDrive and used as an interactive Web App.
The problem is when user deletes some data in the cell (clears the cell) formula is deleted. Is there any way to disable deleting formula. To make the cell same as it was on init or some VBA macro?
I've been searching answer for all day and please don't suggest me F5-go to-constant-numbers because that is not the solution I need. Any advice would be appreciated. Thank you
