create a control of the type you want send to the subvi, in the subvi. right click on the icon and select "conector pane" (only possible in the FP), add the created control to the conector pane. save your vi. Now you can conect the value to transfer to the subvi.
In the subVI, create a front panel numeric control and wire it to your Format Into String. From the subVI's front panel, conect this new control to the subVI's connector pane. Click the subVI's icon and select Show Connector. The prperty node and reference in the subVI are not needed. After you save the subVI, go back to your main program. On the block diagram you will have to right click on the subVI and select 'Relink to SubVI. After you have done that, you can just wire your result to the subVI.
