Model Builder: Select function does not create any output

Hi,
I'm having problems with a model where the Select function in the model doesn't seem to create the output feature class (FC). I get the attached error before I can even get the model process started. The FC referred to in the error isn't suppose to exist until midway through the model, so I'm not sure why I can't run the model at all. I have tried messing with the intermediate data and add to display settings, creating the offending FC before the model runs, deleting the FC before it runs, making the output a shapefile instead of FC, writing to a new geodatabase and a few other things with no luck.

I isolated all the processes leading up to and including the Select function in a separate model and was able to get it to run correctly. However, when I put the processes back in the original model it "broke". I also made it a submodel and nested it inside the original model, but it "broke".

The missing FC is also required input into another submodel I have in the model, but the submodel has a precondition so it doesn't always run. If I take out the submodel and relink some of the datasets, the model works correctly. I'm guessing the issue is with this submodel but I don't understand why because by the time the submodel needs to use the FC it should already exist from a previous process.

The whole purpose of the model (see 'survey_pts_correct.jpg') is to create points on a line that are at least 500-meters ("as-the-crow-flies") apart from any other point. Converting a line to points spaced 500-meters won't work because this distance is measured "as-the-person-drives".

Does anyone have any suggestions or solutions to this issue? I've included graphics of the model and submodel, the models themselves, a script used in the model and the main datasets in case it helps.

Using ArcGIS 10.1 sp1.

Thanks, Charlotte
