Write String to Spreadsheet

Question

Hello,
I have two Booleans and an alphanumeric string that I want to write to a spreadsheet.  The attached code changes the two Booleans to strings, builds an array comprised of the two Booleans and the alphanumeric string and writes the data in a spreadsheet.  After that, it tells the VI what state to go to next where a similar process is repeated.  I am using a VI called Write_String_to_Spreadsheet_File.VI that I downloaded from this Website to write to the spreadsheet.  There is only one problem.  The Write_String_to_Spreadsheet_File.VI appends data to the end of the file.  I need to be able to replace specific data if values change without changing previously entered values.  Is there anyway that I could modify my code to specify the exact row in the spreadsheet to write to?
Thanks,
Drew

Hello,
Here is the code I've generated.  It uses the FILE INFO.vi to determine whether or not the file exists. 
1) If the file does not exist, the WRITE_STRING_TO_SPREADSHEET_FILE.vi creates the file and writes the data entered in the first row of the spreadsheet. 
2) If the file exists, the Read_Text_from Spreadsheet_File.VI should read in the data from the spreadsheet file and the WRITE_TEXT_TO_SPREADSHEET_FILE.vi should write the new data in the first row of the spreadsheet.  This part isn't working, and I can't figure out why.
Can anyone propose a solution?
Thanks,
Drew
P.S.  I tried to solve my problem by using the Index Array.vi in case 2 to address each cell to be rewritten in case 2 (r0,c0, r0,c1, and r0,c2) individually, but it didn't work correctly either.  I think the problem there was the fact that the output of the Index Array.vi becomes 2 diminsional whereas the output of the Build Array.vi is one diminsional.
