Hi, sorry for the late reply.
The error was because you had assigned a variable called "catbank" but later in 
the test you were calling "catBank" which did not exist as R is case sensitive. 
I have corrected "catbank" to "catBank" in section 9.

Similarly there was an error in section 21 since you were calling 
"item_administered" but in the past you have set a variable called 
"items_administered". 

Further, the test still wont run as you have specified a stopping rule based on 
15 items (section 22), but your items table has only 5 items. Please extend 
your table according to the test or change the stopping rule! 

Finally, i would suggest that you first create this test with items that have 
simple numeric responses before trying to improvise.

Please go through your code carefully to check for inconsistencies.
