circuit conflict

[aymanok]

Hello i have a problem with multisim11: i made two circuits in two separate design sheets they work very well and there was no errors. But when i copied them in one design sheet when i make run the simulator gives error message and cannot solve the problem although each has its separate components. they work good in separate design sheets only. what is the solution?

Hello, thanks for response

the first problem is V2 voltage is 120 v

555 would not take it. it is one of problems but not a only one.

your schematic is a mess.  brush it up, it will make it clear for you and for anyone.

check for not connected wires.

what is a purpose of top part of it  - you do not use it, don't you?.

with hope it helps
good luck

hello thanks for response:

even i hanged volt from 120 to 9 volts still the error

the above circuit to produce dc current in 5 volts

the main problem when i put each circuit in separat designsheet it works good.....but when i put them togerther in one design sheet ( to make a bigger circuit ) they give error

Hello, thanks for response

it looks like I have it fixed .

look at the picture.

I cleaned it and brushed it up, removed\changed  a few components,

the bottom line is it runs now.

with hope it helps
good luck
