Importing PDF into MS SQL - sql-server

Question

I'm sorry for the log post but I am about to pull my hair out. I am attempting to import a PDF into a database.
The main error I am getting is: "Implicit conversion from data type varchar to varbinary(MAX) is not allowed. Use the CONVERT function to run this query."
Some of the coding included below is for a SEARCH function that is not yet completed. Please disregard that area of coding.
Basically I am loading a PDF in the AxAcroPDF1 box. This works great. It then pre-fills out a few of the textboxes. User inputs the Broker Load Number than hits save and a openfiledialog opens and the file is chosen to be imported. This then is where the failed import happens and the error above is given. I have tried many different avenues but always ending up with the same result. I am at a complete and total loss.
Table structure is as follows:
ID, int, NOT NULL IDENTITY(1,1) PRIMARY KEY,
BROKER_LOAD_NUMBER nvarchar(15) NOT NULL,
PDF_FILENAME,nvarchar(50) NOT NULL,
PETS_LOAD_NUMBER nvarchar(10) NOT NULL,
PAPERWORK varbinary(MAX) NOT NULL
My FULL code is as follows:
