Estimate Software Problem

Sounds like something their support needs to look at.

 

That's a coding issue in the program itself or you are trying to do something that they didn't intend for you to do in the program. It's trying to convert a Double variable into an Integer but I am assuming the Double is too large to be treated as an integer. In other words, only Estimate can help you.

 

Overflow with integers, at least with my experience in javascript, indicates an issue with variables and what's stored in them.

Could be that solution to the process lays outside the range that the data is able to replicate.

In any event, like was already mentioned, it's more then likely going to need to be looked at by support.
