Answer 1

You are trying to set this string "ViewBuildingInfo.aspx?bId=" to a double variable.

Answer 2

hi Galactia! there is one observe lacking from this proper morsel... that is. the floor isn't meant to ripple like that! (Exclamation aspect to expose excitement) that is as if someone had lifted up an fringe of Guam and shook it (ditch the comma) like a carpet. " n't " shortens "isn't". Make the fact exciting and under no circumstances get into the habit of reducing off the information with a comma. enable the completed series flow... the in worry-free words time you take advantage of a comma is once you're making use of a preposition: 'yet' or as a change of making use of 'and' also once you're string a bunch of information at the same time.

Answer 3

Probably you are passing double value to a string
