Really stumped now

[Milfredo]

I thought I had fixed my problem. In fact I marked post solved. The following code works as long as user selects Race 1. But select any other race number and it won't print out. Throws the following error.

def load_track_to_Handi():
	my_tracklabel= Label(root, text ="                                                                               ", fg= "#F50808", font = ("sans_serif" , 16)).place(x=380, y=430)
	read_csvfile_into_array()
	
		
	global track_abrev
	global race_number
	global xx
	
	#if fileFound ==True:

		
		 
	
	
	hcount = 0
	
	with open( 'C://guis/f_racefiles/'+ track_abrev + '.csv' , 'r') as race_file:

		
		df = pd.read_csv(race_file, header =None)
		
		xx = df.iloc[ :,0:19 ].values
		
		

		for i in range(0,len(xx)):
			if int(xx[hcount][1])== int(race_number):
			 
				print(xx[hcount][18])					
				hcount+=1	

Select race 1 and this is the print out:
TICKET TO RICHES
FLASHY PATCH
HAUTE PROSPECT
MISS VICKI
HONEST GINGER
ABOGADA
But if any other race number selected it throws this error:

Exception in Tkinter callback
Traceback (most recent call last):

if int(xx[hcount][0])== int(race_number):
ValueError: invalid literal for int() with base 10: 'AP '


I don't understand this at all. I thought the [1] in the code stood for column 1.
