3 conditions in one

Hello.

[blk.test;if [val]=1;then 'Yes';if [val]=0;then 'No';if [val]=-1;then 'N/A']

something wrong? It doesnt work.

Hello,
You can have only one 'If' parameter.

my be there is any way for 3 values comparing?

For me, the best way is to use a event function for this field.
An event function is called by using the onformat parameter.
