put only lowercase to dictiomaries and access normally with []
What is char? Why time? How are you splitting morse words/characters?

if text == char: should yield an error since "char" has not been declared. If you want to test for letters it is easier to test for dot or dash as the if and use letters in the else (asuming there are no periods or dashes when letters are input).

## frommorse first
if "." in text or "-" in text:
# or
# if text[0] in frommorse:     ## assumes text does not start with dot or dash
    morse_list = list()
    for char in text:
        ## replace the following two statements with
        if char in frommorse:
        ##for key in frommorse:
                ##if (char.lower() == key):
                        value = frommorse[char]
                        morse_list.append(value)
        ## allow for errors in entry or in the dictionary (like no lower case "z")
        else:
            print char, "not in dictionary"

else:
    ## tomorse code

You can use
if char in string.letters:
as a test for letters vs. dots and dashes.

Print the dictionary, frommorse, somewhere in the code. A dictionary can not have multiple keys that are the same, so it does not contain what you think it does.

You can do:

text = raw_input('What is the translation you need?\n').lower()

and only include lower case in tomorse and

frommorse = dict((b,a) for a,b in tomorse.items())

i got it like that now ..
its running smoothly but i dont know why it isnt printing what .- is or when i input dots or dashes in the program when it asks for something

You can use a function instead of two separate blocks of code, maybe, but that is possibly because I don't understand how you separate receiving ".-"; is it "et" or "a", and if there is a space between, i.e. ". -" vs ".-" then you have to split the input first.

import string

def to_from(text, dict_in):
    for char in text:
        if char.lower() in dict_in:
            print "%6s" % (dict_in[char]),
        else:
            print char, "not in dictionary"
    print

tomorse ={'a': '.-',

I got it to work, after cutting out most of lines. I do not know how OK it is to post it but here it is anyway:

tomorse = {
