Unix script error

I have a unix script (validint.bash) that continues to give the following error after I type the file name and following input...

sh-3.2# bash validint.bash 123.45

Then I get this error message...

: command not found 3:
'alidint.bash: line 4: syntax error near unexpected token `{
'alidint.bash: line 4: `function validint() {

I attached the script below in a text (.rtf) file. Please help. Thanks.

Both of you have great points. I made the changes woolmilkporc suggested. I also transferred the code from Sublime2 to MacVim after experiencing similar errors and it worked. I had another script "validFloat2.bash" referencing the previous script named "validint2.bash" and it worked but I also received this error message.

input
sh-3.2# bash validFloat.bash 1234.56

output
validint2.bash: line 12: [: missing `]'
validint2.bash: line 19: [: missing `]'
validFloat.bash: line 32: [: fractionalPart: unary operator expected
1234.56 is a valid floating-point value

Any other suggestions.

Thanks. The comments on variable assignments, carriage returns and choice of code editor helped!
