form result to metamask

411 views Asked by At

I'm trying to use the input from a form to create the details for a metamask transaction, taking form address and etherem amount then calling them with metamask. The metamask code works when hardcoded with address and amount. not sure where I'm going wrong.

run npx serve because metamask can be tricky.

inside your fill_amount & fill_address functions you’re using the same variable of payment address. I believe inside the fill_amount function the variable should be amountEth not paymentAddress.
