>I have a work order form that allows users to enter work order info and to populate two child tables (via grids) in order to specify labor and materials. The form uses local views. The child labor and materials views have optimistic table bufffering set (5). The "parent" single record work order local view has optimistic row buffering set (3).

>If i add a NEW work order and enter in child labor and material records, i can save the work order and its child information. However, when i try to EDIT an EXISTING record, by changing something in the labor or material grid, the TABLEUPDATE(.t., .t., "v_worklab",laError) fails with the error message of "syntax error". This is nothing else stored in the error array.

Now that you've solved this, just a remark: the array mentioned as the last parameter does something in case of... well, what help says:
"Specifies the name of an array created when nRows = 2 and changes to a record cannot be committed. The array contains a single column containing the record numbers of the records for which changes could not be committed."

To get the errors, use aError() whenever sqlexec() returns 0 or less, or tableupdate() returns .f.
