HTTP POST for multiple parameters in body using SIM900 and Arduino

Hi all,
I have been working on a project using Arduino and SIM900A, which uses HTTP POST request to post 8*8 pixel data ( = array of 64 data) to a Server .

But while uploading with multiple parameters, i am getting one error after "content- disposition: ..." line.
I couldn't figure out what could be the reason for that because the same format is working for single parameter.

please look at the Serial monitor output ( Error) and guide me with this.

AT+HTTPPARA="CONTENT","multipart/form-data; boundary=----------AT+HTTPDATA=192,40000

OK

Content-Disposition: form-data; name="color"

ERROR
