Amend a Pinescript

I have a 250 pinescript that assesses levels for daily vwap and the purpose is to compare price to vwap and vwap to poc and vwap to hourly and minute support and resistance and provide a figure for risk reward above vwap or risk reward below vwap. The calcultion is not working correctly and a new vwap calculation is required as the current one is not correct. I have the correct POC script that is supplied. Its POC and volume profile needs to be set to Day time period. Currently it changes according to time in view.
