** Version 1.1 Notes ** Minor bugs: 1. After using BIOCHLOR, the formula bar would not show up in Excel unless the user went in and selected it to show. This has been corrected by adding a line of code to the autoclose subroutine that tells Excel to show the formula bar when the user exits the software. 2. On the input page, if the user left the zone 1 length cell blank and pressed the "c" button, they would get a macro error. Now the will get the following message: " Please enter a zone 1 length greater than 0". 3. If the user pressed "RESET" on the input page, a formula would be pasted into the "distance to source" section in the field data section. Although the user could override this with any data they chose, the default would be increments of model length/10. This was an inadvertent carryover from BIOSCREEN. Now, when the user presses "RESET", those cells are set to blank cells. 4. On the Natural Attenuation Scoring sheet the formulae for Carbon tetrachloride, ethene/ethane >0.1 mg/L, and chloroform material released were incorrect. These have been corrected to yield the correct scores. Major bug: On the array page, we recently discovered that the mass balance in units of gallons is incorrect. The error would be obvious to the user. It has been corrected to yield the correct mass balance when units of gallons are used. THe mass balance when kg are used remains correct.
