Hi @Mahasri01,

As I understand on the third screenshot, it looks like you're clicking the "Buy" button of the record and MetaMask window does not pops up.

What I'm wondering is, did the bottom right MetaMask notification pop up after you click the button? If so, can you check Chrome DevTools if any issues or errors have been occurred after you click the button?

I just tried the whole platform with a clean environment (downloading the source code and installing from zero) and everything works fine:

Probably you're aware of these but here are some limitations/remarks:

• Truffle and other required packages may be not loaded, you can try to install again with npm.
• The file contents you have uploaded must be separated with CR + LF for every line. Otherwise hash function tries to calculate the whole file and writes into the blockchain. This may cause inconsistent states for the platform.

If you checked these cases and the issue is still happens, can you send a screenshot of Chrome DevTools console for errors/warnings after you clicked the button?

Hope it helps.

Here, I attached the console screenshot.

Here is my console screenshot:

I think your last warning causes this problem but I'm not sure.

代码逻辑有点问题，在已经发送的数据请求（支付页面）中，因该是要判断卖方批准且买方未确认，然后确认购买后卖方和买方的请求批准字段都变为true然后在已购买数据才会正常显示和下载。代码中好像写反了
