Combine two pieces of code together

I found some code to help with the text being too small to read in the drop down list. It is a double click to open a combo box. I have now created code to open a comments box when a certain condition is not reached. When I try to combine the two codes my comments box code doesn’t work.
How can I combine the two codes to make them both work and most importantly, why is breaking?
Below is the code combined.
Note*** if I do not activate the combo box the other code works and the comment box code works like it is supposed to.
