Inline variable substitution in ModelBuilder with submodel

RebeccaFuda

I have a model that uses two iterators, and so I am using submodels.  However, I am having trouble getting my main model to recognize inline variable substitution for a variable from the submodel.  When running the intersect tool after running the submodel, I get the following error: 

Executing (Intersect): Intersect "E:\BFuda\GIS_Data\Properties_For_Sale\overlap_layers\sg_cor.shp #;E:\BFuda\GIS_Data\Properties_For_Sale\parcels_final\analind.shp #" E:\BFuda\GIS_Data\Default.gdb\%Name_wl% ONLY_FID # INPUT

The table was not found. [%Name_wl%]
Failed to execute (Intersect).

The model and submodel are shown below: 

The inputs for the Intersect tool are shown as follows:

I solved this problem by designating the Name_wl variable as a parameter within the submodel.  Then within the main model, I right-clicked on the submodel and chose Make Variable | From Parameter | Names_wl.
