I was wondering if I can disable the submit button until two fields have the same value.
For example I have total amount and total paid amount that needs to be equal.

Without coding your own module for this in javascript, I think it could be done using a calculation and the IF method.
You can use an IF Else statement to put a valid value into a field or an invalid value.
For example a number field with a range of 0-1 could be populated with 0 when the fields match or 2 when the fields do not match.
You can't submit a form when a field has an invalid value.
This field could be hidden, and a field rule could be used to show a proper message letting them know why they can not submit.
