I am trying to write an excel if statement. I am new to using all the extra functionality Excel has. I am using a function called importXML(). I am trying to check whether a function I am using generates a "#VALUE!" error as follows:

if(
   importXML(B1,C1)!="#VALUE!" //check if no error generated, 
   importXML(B1,C1)//if no error is generated, use these cells in the function
   importXML(A1,C1)//else use these cells in the function
)

Is this possible? Am I using excels if statement correctly to check for errors?
