help with php + mysql

Recommended Posts

So, I don't really know how to achieve this with php, so any help would be much appriciated. I bet this is so simple of a solution, I'll look like an idiot.  :-\

 

So.

 

I have 2 MySQL tables.

 

I wan't to take an value from a cell on table 1, substract that from a cell from table 2 so that the new value saves to the cell on table 2.

 

Like: money - item_price = this much money

 

Thank's in advance!
