Erro em calculo de campo

Olá, estou tentando calcular o valor de dois campos em um terceiro campo dentro do meu formulário. Ao criar a formula aparece uma mensagem pedindo para eu corrigir os erros antes de prosseguir e não me deixa salvar a condição. Porém não consigo identificar qual é o erro, já usei essa mesma formula em outros formulários antes e esse erro nunca ocorreu. Poderiam me informar onde está o erro?

Olá, já consegui resolver

Hi Casa_Fitness,

Thanks for reaching out to Jotform Support. Our Portuguese Support agents are busy helping other Jotform users at the moment. I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in your language, let us know and we can have them do that. But, keep in mind that you'd have to wait until they're available again.

Let me get back to your question. I saw that you were trying to add two fields. Keep in mind that if you want to get a number value, the field should be set as 0-9 so it will capture the number value of the fields. If you set your field as A-Z, it will capture the string value of the fields. It's good to know that you've found a solution.

Reach out again if there’s anything else we can help you with.
