Hello i have 3 Listboxes with a lot of values

Listbox 1 (name: #box1) contains "Material ID" etc....

Listbox 2 (name: #box2) contains "Spec ID" etc.....

Listbox 3 (name: #box3) contains "Sampleplan ID" etc....

Thanks a lot. This helped me a lot.

Solution:

If(Wildmatch(concat(#PRODUCTS,','),'*Material ID*') and GetSelectedCount(#PRODUCTS)>0,0,-1)  and

if(Wildmatch(concat(#SPECS,','),'*Spec ID*') and GetSelectedCount(#SPECS)>0,0,-1)  and

if(Wildmatch(concat(#SAMPLEPLAN,','),'*LVL2 ID*') and GetSelectedCount(#SAMPLEPLAN)>0,0,-1)
