MTF indicator code

 
Hello Can anyone see what is wrong with this code. It is an MTF indicator for MT4. It shows for most timeframes correctly but for example so H4 and daily no lines are shown. When compiling, there is a warning that "not all control paths return a value" Line 62 column 4. I can not program so I do not understand what needs to be changed. Thankful for all the help from you who are good at this.
