You don't need to cat the file and pipe it to sed, sed can read the file directly. The problem seems to me to be the quotes. I believe this is what you need; double quotes round the expressions that you wish to have shell variables expanded in.

You might also consider logic like the sample below, so the sed is executed with the correct number of expressions when the user does not enter 'yes' at the prompt:
Note that $p2 is purposely not in quotes on the sed command.

And one last thing....
I'm not quite sure what your sed is trying to accomplish. If I had to guess, I would say that you are trying to use sed to print all lines in the file that contain either string1 or string2. At least when I run it, with that assumption, it isn't doing that.
If that is what you are trying to accomplish, I'd suggest the following:

ssastringcpy
SSAStringCpy(3SNMP) SNMP Library Functions SSAStringCpy(3SNMP)NAME
SSAStringCpy, SSAStringInit, SSAStringToChar, SSAStringZero - Sun Solstice Enterprise Agent string helper functions
SYNOPSIS
cc [ flag ... ] file ... -lssasnmp [ library .. ]
#include <impl.h>
void *SSAStringZero(String *string);
int SSAStringInit(String *string, uchar_t *chars, int len, char *error_label);
int SSAStringCpy(String *string1, String *string2, char *error_label);
char *SSAStringToChar(String string);
DESCRIPTION
The SSAStringCpy() function makes a deep copy of string2 to string1. This function assumes that string1 has been processed by the SSAS-
tringZero() function. Memory is allocated inside the string1 and the contents of string2, not just the pointer, is copied to the string1.
If an error is encountered, an error message is stored in the error_label buffer.
The SSAStringInit() function copies the char array from chars to the string instance with the specified length len. This function assumes
that the string instance has been processed by the SSAStringZero() function or no memory is allocated inside the string instance. If an
error is encountered, an error message is stored in the error_label buffer.
The SSAStringToChar() function returns a temporary char array buffer for printing purposes.
The SSAStringZero() function frees the memory inside of the String instance, but not the string object itself.
RETURN VALUES
The SSAStringInit() and SSAStringCpy() functions return 0 if successful and -1 if error.
