Text does not display correctly

Hi I installed your pop up a couple days ago and created a pop up
I spent about four hours writing and formatting the text and
when I cam to test the pop up I was shocked

the text did not display on the pop up as I created it in the editor

text that should have been on two lines showed up on one line and I spent hours trying to work out the issue but everything I tried failed

the pop up would be great for an image but is in need of some work for displaying text

is this a common issue or just me

thanks
steve
