I have done some working on for Total Resistance, VD across R3, R4 and total current from voltage source
either my calculations are wrong or i am doing something wrong in the program,

can anyone just take a look and tell me if i have made an error as im very green with this program or how it works

 

As you haven't told us what values you calculated and what values Multisim is giving you, how can we know if/what any error is?
Why are R5 and R6 shown as shorted?

 

sorry that would help wouldnt it, RT i have 5.68K ohms, Total Current 2.11mA. VD 5.43v
and i have made an error on the drawing as you pointed out

 

Are those the values you calculated, or are they from Multisim?
Have you eliminated the error?

 

i calculated them first, and wanted to confirm with multism, the error confirmed the working out was correct
