TagExists function in WW does not exist

[IamJon 0]

we have a program in wonderware 7.11 p6 which has been running. when we go into the script functions, there is a function called TagExists. a validation of the code reveals that this function does not exist. we had the local engineer check to see if the add-on was installed on his computer, and it was, but he still couldnt recognize the function. anyone have this or similar problems before? and more importantly, a solution. we'll be contacting ww support soon. edit: turns out the add-on was running on the hmi but not his personal pc, so he just needed to reinstal it.
