HTH test kit -Chlorine test probs!!!?

hi i have a HTH test kit that i use to test the water in my pool ,When i bought it ,it came with little tablets to test the chlorine in the water it used to usually change to a pinkish colour ,but those tabs got finish and i replaced it with the hth Chlorine test which is liquid. the instructions are 'add 5 drops 2 the test cell' but my water remains clear. please tel me what am i doing wrong?

1.you could have too much water in the test cell 2.you could have very low chlorine 3.you could have very high chlorine and it is bleaching out the reading 4.you could have old reagents buy a new test kit(i recommend the taylor kit)
