Report based on a variable

Just for fun I decided to try this but I can't figure out how to use anything other than a global variable.
In WinDev22 I created an Invoice class which contains all of the header and detail (Invoice lines).
I created a variable on the window that shows the Print Button but that is obviously the wrong place because the Report does not seem to recognize it. I even passed it as a parameter to the report.

Hello Garry,

Yes this can be done. I have a class that fills the data of the variable from the window and when it is time to print a pass 1 array for the rows and 1 structure variable for the header of the class to the print window.

The button from the window

clTrInstall is clTRInstallList

clTrInstall.cm_TR_InstallQuery(nLoadID)
clTrInstall.cm_ReportHeader(nLoadID)

iPreview(100)

iPrintReport(RPT_TR_Load,clTrInstall.m_arrInstallList,clTrInstall.m_LoadInfo)

//In the report the same arrays from the class are used.

PROCEDURE RPT_TR_Load(arrInstallList is array of clTRInstallList.stInstallList,gstLoadinfo is clTRInstallList.stLoadInfo)
