I’m developing a sales website and it has a product Lettering and each letter costs R$10,00.
How to calculate the value of a phrase the customer wants to buy?
For example, if the customer wants to buy his name, Betinho. The amount would come out for R $ 70,00 real.
How I do this validation and accounting through an input?
Ola Betinho Silva, Just now I had time to see what you asked there in the other post
