I have a variable named "MaxNumber". I want to create a chart expression like:
IF $(MaxNumber) is empty then... else...
What is the exact syntax? I tried to use '' or "" or ' ' but it doesn't idntify the empty variable. Also, ISNULL() doesn't recognize "empty" as "Null"...
try the following instead of empty and so on. (Note the two '' around the Var):
If( Len( '$(Variable1)') > 0, . . .)
You can also use the isnull() function. like
