i am using the following line of code in my combo box to filter
out the materials i will be using in my table i call the material
mat. the line of code i am using in the afterRowColchange of my
grid:
lcFilter = [Set Filter To mat="] + mat + ["]
&lcFilter

This code works fine, and I know how to use the filters
on tables. I don't understand what the brackets, quote and plus
[+"] symbols are doing.
