0 code is looking fine by the looks of it. Just check for null value, before appending it to the string builder..
0 I think is the way i organized the (') or ("") in these lines
sqlBuilder.Append(
frmAl.tbQrtResp2.Text + "','"); //9
sqlBuilder.Append("@PicResp2,'"); //10
sqlBuilder.Append(frmAl.tbCasaResp2.Text + "')"); //11
it shows there's a error near the last line
0 What error you are getting?
