8150 Easy javascript

Need to make a input field evaluate an expression on onBlur. The function that is run onBlur should do the following things: clean string from letters and spaces, change "," into "." and then it should make a calculations from input so for example if a user inputs "10+5" it should return 15 (3*15 should return 45) etc and then finally it should check if number returned is numeric for sure. If not it should give an alert error. I almost have the function completed but it does not make the calculation from field input. I am trying to use the eval component but to no avail... Please show working solution on message board and then you will be chosen and paid. Easy job, and guaranteed easy good review.
