IF or IFS Help

Hey Everyone,

Need some help with an IF formula that is getting an #UNPARSEABLE error. Below is the code that I am using to get this error.

=IF([# of POS]@row="4 POS", 26,0) IF([# of POS]@row="5 POS",28,0) IF([# of POS]@row="6 POS",28,0)

Any advice on correct codding would be great appreciated.

Thank you
