Your graphic doesn’t work.
You are doing data entry instead of copy and paste. Always a problem.
First order of business should be accessing the source data directly, which means you have no data entry errors. You may have to massage the data by first plunking it into a word processor to replace spaces with tab characters to produce tab delimited data.
After that, comes the text editor. Copy from the word processor and paste into the text editor to strip formatting that the table doesn’t understand. You immediately select all in the text editor, copy, and paste into your matrix.
Usually, number dependencies are created during data validation type operations. However, when you create dependencies, there is typically source data and result data. Entering data into one cell can modify another but entering data into the dependent (variable) cell obliterates the underlying equation entered in the cell. Otherwise, you an end with circular logic that will kill your processor as one cell tries to reconcile its value with it’s mate – at 2.53GHz speed.
