PSpice error while simulating 555 ic

[ravi2024]

Hi!
M new to Pspice.. (have to use it for a project). while simulating a simple 555 IC circuit in Pspice i am getting the following error msg. Could anyone tell me what should i do to resolve this?

Error Msg:

The error is the space in the R2 resistance value.

Hi!
Thnx for the suggestion.
The output pulse i am getting now is of 4.5 V. I want the desired output pulse of 20 Volts. How can I arrange multiple of these 555IC circuit in series to get 20 V output?
