Hi Brett,
the problem is that the File Variable cannot read a file on a network drive. It has no arguments for rights. What you can do is either:
1. Create a file read Task and then, in this SQL Task you use the output of the previous File read Task. Use this Variable then: {TASK(PrevTask,StdOut)} - remember to add a Credential to the file read Task
or
2. Use a local file path instead
or
3. Copy the file locally using the Copy files Task. Please remember to use a Credential then
