Problem with Query....

Hi there,

Simple query that I cant get to run, this is the query:

SELECT m.*, mt.restricts, b.Module
FROM mat_trnkld m, matprt_trnkld mt LEFT JOIN BOM b
ON m.PartNo = b.partnumber
WHERE m.PartNo = mt.PartNo
AND m.SubProd = '50'

and I'm getting this error:

Msg 4104, Level 16, State 1, Line 1
The multi-part identifier "m.PartNo" could not be bound.


Thanks,

Stelly
