Change the years to calculate a loan

The If Statement goes like this

If(condition, value if true, value if false)

 Your formula syntax needs to be fixed

=if(e22="","" ,PMT(H22/52,$L$22*52,-E22,0), 0)

-You have a premature closing bracket for the if statement (removed)

-You don't have a value if the condition is false. I assumed you want a zero, but you might want something else.

-I don't know if your condition works since you haven't told us anything about e22.
