Forms :: Display Record Counts / Unique Names

I have a table

TAB1 with data
no name
1 abc
2 abc
3 xyz
4 xyz
5 cvb

now I would like to create a form with name counts as

abc 2
xyz 2
cvb 1

I would like to create a datablock to display all the unique names, not sure where I should be writing the query to display unique names. I would like to create a textitem box to display the counts when the form is compiled, but not sure which trigger to use to write the query.
