Attach CV not working

Hi,

I'm using the API on a website to write candidate data into Zoho recruit. It mostly works fine except the attach file doesn't work. I've searched various forums and found a number of people have had this issue.

I am using base64 to encode the file, I'm using the <FL val=" 1 - Attach resume "> parameter and leaving a space before the attachment name (something that was suggested). None of which work. Does anybody know if there is an solution to this? It's also unclear whether I'm supposed to attach the encoded file content or the encoded form variable. I've tried both but attempting to attach the file content stops the whole thing from working.

Any help or advice would be avery much appreciated.

Thanks
