You could consider use of a parameter or a global variable.

Have you considered updating the value in the database in Form B and then requiring the information in Form A?

Easy,

at form B, do assign the global variable to copy the value

for example at form B where the calculation happens

:global.totalB := :blockB.total; 



at form A, form level trigger, when-windows-activated assign the variable back


:blockA.total := :global.totalB;
