Sorry

Sorry to disturb you with this basicly basic question but
 i really need an answer even it is 
certainly a very simple thing to do. Here it is, i simply want to multiply,add,
 the value of two 
variables
 and i can't
 i know


My code :

on mouseUp
  put the number of characters of field "myfld" into MyChar
  put the value of field "price" into MyNum
  put MyChar * MyNum into field "devis"
end mouseUp

it returns an error in the right operand while the structure seems bascily logical

Please help !
