I have been having real difficulties try to insert a 20 column record into a 
table (using PHP not MySQL monitor). If I hardcode I can add a record 
.Taking the script that works I then doctor it substituting the hardcoding 
with $_POST values and then fall over (meaning no record is written). I know 
I have got to the point of writing away a record by putting a checkpoint 
just before the write. I have tested the insert-record-into-database with a 
smaller database of 4 columns and it all works fine, but with my MySQL 20 
columns it just doesn't work can anybody see what I am doing wrong?

This works
