Hey guys...
I'm attempting to capture multiple lines of text (Like a paragraph). I must be missing something here. I'll have a text like this, though it may be more or less lines. Also, each line is seperated by a line break. (\n)

am I missing something ? Can someone help me?

i.e.
Requirement: SCD:FCE2752
Identifier: HRD_COM_001840
Identifier: [PCM_HRD_HEIN_0120_00]
                 Case grounds shall be used to conduct fault current only and not used as a normal current
                 return path except for EMI filters, which may be connected to current return and chassis.
Requirement: SCD:FCE2753
Identifier: HRD_COM_001841
Identifier: [PCM_HRD_HEIN_0121_00]
                 LRU power return and chassis ground wires shall be of the same or larger gauge (current
                 carrying capacity) as the power input wiring.
                                                           NOTE
                          The returns should be sized to be fault current return path.

So has to make the dot match anything, including line break etc, you must use the "single-line" modifier, I do not know which language you are using so check your documentation.
