Doing a calculation based on the entries made by a user in two seperate form fields - possible?
My client has asked for a form where the user selects values from a drop down menu. Those values have a monetary value, for example
<input type="text" value"350">
Number of Pets:
Pets are charged at £15.00 each and the insurance is £16.00 so, in the above example, if a user selects 2 pets and insurance I need it to add £46.00 (2 x £15.00 and 1 x £16.00) to the Rental Fee value (£350).
Is this possible via validation? Show If?
Would appreciate your advice. Thank you.
