What does this error mean

[mechatech]

I have this mod vipcxj High Heels installed and it works. But I am getting this error in console since I first started using it.

Error in script ab005a06
Operator := failed to evalutate to a valid result
     File: VipCxj_HighHeels.esp Offset: 0x02AB Command: Let

What does it mean? Can I fix it? Should I fix it?

 

 

edit - doing a clean save and reinstalling the mod removed the error, at least for now but I would still like to know what happened.

In one (assuming there are more than one) of the mod's scripts,a line failed for some reason while it shouldn't. I don't know exactly how the mod works but maybe you wore shoes that messed something up (just a wild guess of course)?

A "let" command in the script is trying to set a pointer to a null value. I think that the problem is not the mod, but the savegame.
