Percentage Counter

Hello! I am looking for advice/solution to help me understand what is going wrong with the variable I am using for counting a percentage for an upload document prototype. We want to show visual feedback of percentage of the document that has been uploaded.

I am currently using this variable, and on delay I want the number to count from 0%-100%; however, I am only able to get the number to count from 0%-2% & that is where the variable stops working.

Any idea on what else I can use, or what the issue might be? Thanks in advance!
