Row 75 of your XLSForm has an undefined survey element Other(Specify), it looks like you wanted a survey element from Row 74 - Other_activities2
Your XLSForm has other errors (for example: there are multiple survey elements with the name: total_calc), you can test, preview, and validate your forms here
I strongly suggest you go through the XLSform Tutorial: Your first form
