Using Arrays

[Van Brollini]

on mouseUp

get the dgdata of group "DGTester" 
put it into tArray	
put the keys of tArray	

Repeat with x = 1 to 1249

put "3.76" into tArray[x]["usl_lcb"]
end Repeat
set the dgData of group "DGTester" to tArray	
end mouseUp

putting a breakpoint at the end mouseUp shows that 3.76 was successfully entered into array

and the datagrid was NOT updated. What did I do wrong? Or what am I missing.
