>>Hi all
>>
>>I have a parent table with a field that hold the ID from a LOOKUP table so that in a browse window I can set the parent relation into the LOOKUP table and display what the ID represents.
>>
>>EXAMPLE: '0001' is 'EAST', '0002' is 'WEST', '0003' is 'NORTH' etc...
>>
>>In the browse I want to set the order by the column which gets its content from the LOOKUP table and order the parent table accordingly.
>>
>>Can anyone tell me what is the best way to do this.
>>
>>Thanks much in advance.
