Hi capt_jmj, about thet TA lib.
The TA lib is an excel add in as you all know. The only reason for ?name to appear is that the add in is not loaded.
Many things could make that happen, one of them is moving the add in from its folder or in general to modify the path to it. Some bad programming in other add is could unload it as well.
The procedure to restore it is rather simple:
Go to tools/add in
look for the TA lib and it should be unmarked, is that is the case check it. It should work now.
BUT If the add in is already checked, uncheck it. In this waS the case, porbably you will receive a warning message that the add in could not be found and ask you to delete the link, say yes, and then browse to the file and load it again.
hope it helps
