Processing issue with callback function in Access

[LLBP]

I have an Access form setup to accept user input as static information. I then have an I/O card installed (PCI-7224 from ADLINK) to aquire pass/fail results from a RunCheck/PLC system. I want to create records using the form data and aquired results. The I/O card has an interrupt function that accepts a callback function address as an argument - interrupt occures, it calls the said function. This same function works perfectly when called from a cmd button on the form. It seems to be unauthorized to write to any table - local or SQL Server, when called from the interrupt. I can query tables, call other functions, change properties on my form using the interrupt callback function but cannot write data. I have declared all functions as public.

Can any one give some advice, please?

Thanks in advance.

Do you gett any error messages or does it simply not write to the database?

No error message at all. Thanks for reviewing my issue!
