Link getting cut off when importing from txt file

I have a text file that the client updates and I load the var into a flash file

&coordinate_1=39° 30’ 42.28” N    101° 14’ 29.73” W

but when you clik on a button that is linked to the “coord_link” it cuts off the url at the = sign

so the links look like this the the new page open up, not good…

anyway to work around this
