You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'molding_section.machine_name, intermediate_store.product FROM molding_section, ' at line 1

but i cannot figure out the error

now this is the error how can i remove it

[sidra 100]

now this is the error
Column 'shift_id' in where clause is ambiguous

[cereal]

Do you have shift_id in both tables molding_section and intermediate_store? If yes, you need to change the where clause to: WHERE molding_section.shift_id='$shift_id' AND intermediate_store.shift_id='$shift_id'
