Hi,
Please don't be so cryptic. Most of the questions you posted on the forum do not provide enough information. I admire the patience from experts like Krishnasandeep and AV who are really trying to understand and make sense in your issue based on threadbare information.
Please provide complete information on the issue. What you are trying to do, what error are you getting, what code have you written etc. Provide screenshots to elaborate on the issue and error description. People spend lot of time and effort on this forum. Please make it worth by providing adequate information.
Ravi
