Problems with Adding own mob models

Hi everyone, i'm very knew to this scene of modding, i have bee experimenting with modeling mobs, cuz its what i like the most but i been getting problems when i tried to add the model to the mccreator, at first i didn't add them for some reason and while did some research i found out that the problem was the program that i was using for modeling, which was Techne, i changed to blockbench and exported all my models to it, from there i tried to put them again on the mcreator ad a java archive as i did before( using the export to java in blockbench) but every time i put my own models it says "Make sure all the model parts have a valid java name and that your model is in fact a java model with a valid syntax" i really don't know what to do from here so ig you help me i would really appreciate it, Thanks :)
