Hi Peter. 

I tried your method and it worked. I'm still a bit nervous at this point 
because of the problems I have had using the arrays and such so for now I am 
going to use dgText. The data in these particular datagrids is never going to 
be very much data, but later when I work with larger data sets I will need to 
use this.
