I've been thinking about how to get this idea work: I have a table in my page. Four columns and several rows. Columns are (1) a product name, (2) how many needs to be purchaced, (3) how many already have been purchased and (4) a submit button which should add always one more in column 3.
Every product should have a default value in column 3 as 0. And every product should have a max value in column 3.
Now I can't figure out where to start. Obviously PHP+MySQL could act as instruments here but either way I don't know how to start doing this.
Could someone offer a little help?! Give a boost to this project!
