Bind table data to a drop down control

I am attempting to bind a list of operator names to a drop down selection control.

I’ve had partial success creating an SQL tag but it appears to be attempting to write to the table and after selecting an operator the control goes red and locks up.

I’m very new to this and any help would be appreciated.


Can you paste your query here?
What exactly leads you to think that the query is writing to the table?
