First of all, I am new to Jasper reports myself, but I experienced the same problem. If anything I mention below is wrong feel free to correct me.

In your parent report "Samplemainreport" select the subreport... you need to provide the directory of the subreport in the subreport expression properies box.

i.e. $P{SUBREPORT_DIR}+"name of subreport.jasper" (that is if you save your subreport in the same directory you save the main report)

Than in Parameters Map Expression choose $P{REPORT_PARAMETERS_MAP}

From the looks of it... that should be all you're missing. Just make sure your  parameters in the subreport are the same as your parent report.
